Molly Duplass is the daughter of actor, filmmaker, writer, and producer Mark Duplass and actress-director Katie Aselton. She attracted public attention in 2022 after appearing in her mother’s comedy film Mack & Rita, where she played the younger version of the main character, Mack.
Although Molly comes from a well-known Hollywood family, she has maintained a relatively private life. Unlike her parents, she has not developed an extensive public entertainment career. Most of the information available about her comes from her connection to the Duplass-Aselton family and her appearance in Mack & Rita.
Her story is therefore best understood through the information that can be reliably documented rather than through speculation about her private life, education, finances, relationships, or future plans.
Who Is Molly Duplass?
Molly Duplass is one of the two daughters of Mark Duplass and Katie Aselton. Her parents have both established careers in American film and television, giving Molly a close connection to the entertainment industry from an early age.
Her father, Mark Duplass, is known for his work as an actor, filmmaker, writer, and producer. He and his brother Jay Duplass became prominent figures in independent filmmaking and later expanded their work into television and documentary production.
Her mother, Katie Aselton, is an actress, director, and producer. She has appeared in television series and films while also working behind the camera as a director.
Molly became publicly recognizable because she appeared in Mack & Rita, a 2022 comedy directed by Katie Aselton. Her role was relatively small but meaningful because she portrayed the childhood version of the film’s central character.
Molly Duplass’ Parents, Mark Duplass and Katie Aselton
Molly’s father, Mark Duplass, has had a wide-ranging career in entertainment. Together with his brother Jay, he became associated with independent filmmaking through projects that emphasized character-driven stories and relatively intimate production styles.
The Duplass brothers went on to create and produce numerous films and television projects. Their work helped establish them as important figures in American independent entertainment.
Katie Aselton followed a similarly varied career. She became known as an actress while also developing her abilities as a filmmaker. Her acting credits include television and film projects, while her directing work includes The Freebie, Black Rock, and Mack & Rita.
Mark Duplass and Katie Aselton married in 2006 and have two daughters, Molly and Ora. Their family has consequently remained connected to the entertainment world, although the daughters have generally had a much lower public profile than their parents.
Molly Duplass and Her Sister Ora
Molly Duplass has an older sister named Ora Duplass. Both sisters appeared in Mack & Rita, giving the film a particularly personal connection to their family.
Molly played the younger version of Mack, while Ora appeared in another scene as one of the teenagers at a restaurant.
Their appearances were relatively brief, and neither sister should automatically be described as an established Hollywood actress based on these credits alone. Their participation is better understood as part of their family’s connection to the movie and their mother’s work as its director.
The sisters’ limited public profiles also mean that reliable information about their personal lives remains relatively scarce.
Molly Duplass in Mack & Rita
Molly Duplass’ best-known acting credit is Mack & Rita, released in 2022.
The film follows Mack, a 30-year-old writer who feels increasingly disconnected from the expectations placed on people her age. After an unusual experience, she wakes up in the body of her 70-year-old self.
Diane Keaton plays the older version of Mack, while Elizabeth Lail portrays the adult Mack. Molly appears in flashback scenes as Mack at age nine.
Her role helps establish the character’s younger life and gives audiences some context for Mack’s personality and relationship with aging. Although Molly does not carry the film, her appearance is directly connected to the central character’s backstory.
The movie also represented an unusual family collaboration because Katie Aselton directed the film while her two daughters appeared in it.
How Molly Duplass Became Part of Mack & Rita
Molly’s involvement in Mack & Rita was closely connected to her mother’s position as director.
Katie Aselton had already built a career in acting and independent filmmaking before directing the movie. When she made Mack & Rita, the production provided an opportunity for both of her daughters to appear on screen.
Molly was cast as the younger Mack, while Ora appeared in a separate scene.
The arrangement gave Molly an early acting credit without necessarily indicating that she had decided to pursue acting professionally. There is an important difference between appearing in a family-related production and establishing a long-term career in Hollywood.
For that reason, Mack & Rita remains the most important documented part of Molly’s public career rather than evidence of a large acting résumé.
Molly Duplass’ Acting Career
Molly Duplass has an acting credit in Mack & Rita, but her publicly documented filmography remains limited.
Her parents have worked on numerous films and television shows over several decades, while Molly has largely stayed away from the level of publicity associated with professional actors.
There is currently not enough reliable public information to characterize her as an established actress with a substantial body of work.
This distinction is especially important when researching young people from famous families. A single film appearance can generate numerous online biographies and claims that make a person’s career appear larger than the available evidence supports.
In Molly’s case, the most accurate description is that she is a member of a prominent filmmaking family who appeared as young Mack in Mack & Rita.
Whether she chooses to pursue more acting work in the future remains unknown.
Molly Duplass’ Age and Birth Information
Detailed information about Molly Duplass’ birth date has not been consistently documented by strong primary sources.
During the production and promotion of Mack & Rita, reporting indicated that Molly was around 10 years old in 2022. However, the character she played was nine-year-old Mack.
These are two different pieces of information. Mack’s age refers to the fictional character, while Molly’s age refers to the real performer.
Some online sources have published conflicting birth information for Molly and her sister. Because these details are not consistently supported by authoritative sources, an exact birth date should not be presented as confirmed fact.
For a young person who has otherwise maintained a private life, there is also little journalistic value in repeating uncertain personal details.
Molly Duplass’ Family Background
Molly grew up in a family deeply involved in American film and television.
Her father, Mark Duplass, is part of the filmmaking partnership known as the Duplass brothers. Mark and Jay Duplass have worked together on independent films, television series, documentaries, and other productions.
Their work includes films such as The Puffy Chair, Baghead, Cyrus, Jeff, Who Lives at Home, and The One I Love. They have also been involved with television projects such as Togetherness and Room 104.
Molly’s mother, Katie Aselton, has developed her own career as an actress and filmmaker. She is known for projects including The League, The Freebie, Black Rock, Legion, and Mack & Rita.
This background means Molly grew up surrounded by people who worked in creative industries. Her appearance in Mack & Rita was therefore a natural extension of an environment in which filmmaking was already an important part of family life.
What Is Known About Molly Duplass’ Education?
There is very little verified public information about Molly Duplass’ education.
Because she was still young when she appeared in Mack & Rita and has not established a highly public professional career, details about her school, academic activities, teachers, or educational history have not been widely documented by reputable sources.
It would be inappropriate to fill this gap with information from unverified celebrity biography websites.
Her education should therefore be considered private unless Molly or her family publicly provides reliable information about it in the future.
Molly Duplass’ Personal Life
Molly Duplass has maintained a considerably lower public profile than her parents.
There is no substantial body of reliable reporting about her romantic relationships, friendships, daily lifestyle, or other private matters. Much of the information that does exist publicly relates to her family and her appearance in Mack & Rita.
This limited public record is worth respecting. Not every person connected to a celebrity family becomes a public figure, and being the child of famous entertainers does not automatically make someone’s private life appropriate for speculation.
For that reason, claims about Molly’s personal relationships or lifestyle should be treated cautiously unless they come from a reliable and direct source.
Molly Duplass’ Net Worth
There is no reliable public estimate of Molly Duplass’ personal net worth.
Online celebrity websites sometimes assign financial figures to people simply because their parents are successful. Such figures should not be treated as established facts.
Mark Duplass and Katie Aselton have built successful entertainment careers, but their income and assets cannot automatically be attributed to their daughter.
Molly’s own earnings from her acting appearance, if any, have not been publicly established in a way that would support a credible net-worth calculation.
Therefore, the most accurate answer is that Molly Duplass’ net worth is not publicly known.
Molly Duplass and Katie Aselton
One of the most interesting aspects of Molly’s public story is her connection with her mother.
Katie Aselton directed Mack & Rita, and Molly appeared in the film as young Mack. This gave mother and daughter an opportunity to work together on a feature film.
For Aselton, the movie represented another step in her development as a director. For Molly, it became her most recognizable screen credit.
Their collaboration also reflects the broader creative environment surrounding the Duplass family. Mark Duplass and his brother Jay had already spent years working together as filmmakers, while Katie Aselton had developed her own acting and directing career.
Mack & Rita brought several elements of that family history together in one production.
The Duplass Family’s Contribution to Independent Film
To understand why Molly’s name attracts interest, it helps to understand the reputation her parents have built.
Mark and Jay Duplass became associated with a style of filmmaking that emphasized personal stories, realistic characters, and creative approaches to production. Their early independent movies helped establish them within the American independent-film scene.
Over time, their work expanded beyond movies into television, documentaries, and production.
Their influence has also extended to projects involving emerging performers and unconventional storytelling. This broader creative legacy forms the professional background into which Molly was born.
Her appearance in Mack & Rita is only a small part of that history, but it is an interesting example of how the family’s professional and personal worlds sometimes overlap.
Is Molly Duplass Still Acting?
There is not enough reliable public information to say that Molly Duplass currently has an active professional acting career.
Her most recognizable screen credit remains Mack & Rita. No substantial public filmography has emerged that would place her alongside established actors in the entertainment industry.
That does not mean she will never act again. Young performers can take long breaks from entertainment or decide to pursue completely different interests as they grow older.
It simply means that there is currently insufficient evidence to make a stronger claim about her career.
What Is Molly Duplass Doing Now?
Molly Duplass has largely remained outside the public spotlight since her appearance in Mack & Rita.
As of 2026, reliable public information does not provide a detailed picture of her current career, education, or personal activities.
Her limited public presence should not be interpreted as evidence that she has disappeared from public life or abandoned acting. It simply reflects the fact that she has not maintained a highly visible entertainment career.
If she eventually takes on additional acting, filmmaking, or another professional role, that information can be evaluated when reliable sources document it.
For now, the strongest facts about Molly remain her family background and her role in Mack & Rita.
Why Molly Duplass Remains Notable
Molly Duplass remains notable primarily because of her connection to two established entertainment figures and her appearance in a film directed by her mother.
She is part of a family that has played a recognizable role in independent American filmmaking. Her father and uncle built a significant creative partnership, while her mother established herself as both an actress and director.
Her appearance in Mack & Rita also offers an unusual example of a family working together professionally.
However, Molly’s story should not be exaggerated. She is not currently documented as a major Hollywood star, and there is no evidence to suggest that she has accumulated a large entertainment career.
Her public story is comparatively simple: she is the daughter of Mark Duplass and Katie Aselton and appeared as young Mack in her mother’s 2022 film.
