Her Age

She was born on June 30, 1982. That makes her 44 years old as of late 2026. She was 21 when Mean Girls opened in the United States on April 30, 2004. She was 31 when Masters of Sex premiered on September 29, 2013.

Complete Film List

The film side of Lizzy Caplan movies and TV shows runs from a small party scene in 2002 to a studio sequel in 2025.

She also voiced the lead role of Amy Nichols in The Commuter, a 2025 Audible Original audio thriller by James Patterson and Aaron Tracy. It is an audio production, so it sits outside the film table.

Complete Television List

Television is where she has done most of her lead work.

One source lists her True Blood part as a main role for the first season. Another describes it as a guest role. The table above leaves the billing open for that reason.

Career Phases

Early Television Work (1999 to 2003)

Her career began while she was still in high school.

• Freaks and Geeks (1999 to 2000). She played Sara in four episodes of the high school series. Her character became the girlfriend of the character played by Jason Segel. The show did not last long, but critics praised it, and it launched many careers.
• From Where I Sit (2000). This television film gave her the role of Lily. It was her first film of any kind.
• Undeclared and Once and Again (2001). She took single guest spots in a college comedy and a family drama.
• Smallville (2001 to 2003). She appeared twice as Tina Greer in the young Superman series.
• Orange County (2002). Her first theatrical film credit was a small part listed as Party Girl.
• The Pitts (2003). She won her first main role, as Faith Pitt, in this sitcom.

She also appeared in the music video for “You and I Both” by Jason Mraz during this period. The fetched sources give no year for the video.

Mean Girls and the Sitcom Years (2004 to 2007)

Mean Girls changed how casting directors and audiences saw her. Mark Waters directed the film, and Tina Fey wrote the screenplay. Paramount released it in the United States on April 30, 2004. The cast included Lindsay Lohan, Rachel McAdams, Amanda Seyfried, and Lacey Chabert.

Caplan played Janis Ian, an art student and outcast who befriends the new girl, Cady. Janis explains the cliques at the school and warns Cady about the popular group known as the Plastics. She then plots with Cady and Damian to bring down the group’s leader. The film grossed $130.1 million worldwide on a budget of about $17 to $18 million. Janis remains the part most casual viewers name first.

Steady television work followed.

• Tru Calling (2005). She played Avery Bishop in four episodes of the second season.
• Related (2005 to 2006). She had a main role as Marjee Sorelli in this series on The WB. The network canceled it after one season.
• Love Is the Drug (2006). She played Sara Weller in this independent film. Variety named her one of its “10 Actors to Watch” around that time.
• The Class (2006 to 2007). She played Kat Warbler in this CBS sitcom about elementary school friends who reunite after 20 years. It ran for one season.
• Voice work. She began a recurring voice part as Debbie on American Dad! in 2006 and did a guest voice on Family Guy the same year.

Cloverfield, True Blood, and Party Down (2008 to 2012)

This phase turned a familiar face into a lead.

• Cloverfield (2008). Matt Reeves directed this found footage monster film, written by Drew Goddard and produced by J. J. Abrams and Bryan Burk. It opened in North America on January 18, 2008. Caplan played Marlena Diamond, a party guest who gets caught up in the monster attack. The role brought her a Saturn Award nomination for Best Supporting Actress.
• My Best Friend’s Girl (2008). She played Ami in this comedy.
• True Blood (2008). She played Amy Burley in the first season of the HBO vampire drama.
• Party Down (2009 to 2010). This Starz sitcom follows a Los Angeles catering crew made up of would-be actors and writers. Each episode covers a new event. She played Casey Klein, a struggling comedian who tends to ignore authority. Casey starts the series married, then divorces, and begins a relationship with Henry, played by Adam Scott. The cast also included Ken Marino, Martin Starr, Ryan Hansen, and Jane Lynch. Critics liked the show, but ratings were very low, and Starz canceled it in June 2010.
• Hot Tub Time Machine (2010). She played April Drennan and earned a Teen Choice Award nomination.
• 127 Hours (2010). She had a supporting part as Sonja Ralston.

• Item 47 (2012). She played Claire Wise in this short film.

Masters of Sex (2013 to 2016)

Masters of Sex is the centerpiece of her career. The Showtime drama premiered on September 29, 2013, and ended on November 13, 2016. It ran for four seasons and 46 episodes. Michelle Ashford created it, and it draws loosely on a biography by Thomas Maier.

The series follows the sex researchers William Masters and Virginia Johnson at Washington University in St. Louis. Michael Sheen played Masters. Caplan played Johnson, his research partner. She read the Maier biography to prepare and has spoken of feeling a “deep responsibility” to the real Johnson. She also sang a cover of “You Don’t Know Me” in the episode “Phallic Victories.” She served as a producer on the show.

Reviews for her work were strong, especially in the first two seasons. She received a Primetime Emmy nomination for Outstanding Lead Actress in a Drama Series in 2014. She also received Critics’ Choice and Satellite nominations. The role proved that an actor known for comedy could carry a period drama.

She kept working in films during these years.

• The Interview (2014). She played Agent Lacey.
• The Night Before (2015). She played Diana in this holiday comedy.
• Now You See Me 2 (2016). She joined the magician heist series as Lula May, a new member of the Horsemen who specializes in disguises. The part brought another Teen Choice nomination.
• Allied (2016). She played Bridget Vatan in this wartime drama.

Genre Roles and Streaming Series (2017 to 2021)

After Masters of Sex ended, she moved between guest comedy spots and darker lead parts.

• The Disaster Artist (2017). She made a cameo as herself.
• Ill Behaviour (2017). She played Nadia in three episodes.
• Extinction (2018). She played Alice in this science fiction film.
• Das Boot (2018). She had a main role in the first season of this German war series, which premiered on Sky One in Germany and later ran on Hulu in the United States. She played Carla Monroe, the leader of a French Resistance cell in La Rochelle in late 1942.
• Castle Rock (2019). The second season of the Hulu series ran from October 23 to December 11, 2019. She played Annie Wilkes, a nurse with mental illness who becomes stranded in the town of Castle Rock. Tim Robbins, Paul Sparks, Barkhad Abdi, and Elsie Fisher co-starred. The critical consensus on Rotten Tomatoes called her “unsettlingly compelling.”
• Truth Be Told (2019 to 2020). In the first season of this Apple TV+ drama, she played identical twins, Josie and Lanie Buhrman. Their father’s murder sits at the center of a case that a podcaster, played by Octavia Spencer, reopens.
• Inside Job (2021 to 2022). She voiced the lead, Reagan Ridley, in this Netflix adult animated comedy from creator Shion Takeuchi. Reagan is a brilliant, awkward robotics engineer at a shadow government agency. Netflix released 18 episodes in two parts and then canceled the show in January 2023.

Limited Series Run (2022 to 2023)

Three projects in two years put her back in awards talk.

• Fleishman Is in Trouble (2022). This FX on Hulu miniseries ran for eight episodes from November 17 to December 29, 2022. Taffy Brodesser-Akner adapted it from her own 2019 novel. Jesse Eisenberg and Claire Danes played a divorcing couple. Caplan played Libby Epstein, a former magazine writer turned suburban housewife, who is one of Toby Fleishman’s best friends and the narrator of the story. Reviews were positive. She received her second Primetime Emmy nomination, this time for Outstanding Lead Actress in a Limited or Anthology Series or Movie.
• The People We Hate at the Wedding (2022). She played Marissa in this comedy film.
• Fatal Attraction (2023). Paramount+ released this series from April 30 to May 28, 2023. It is based on the 1987 film, in which Glenn Close played Alex Forrest. Caplan took that role, with Joshua Jackson as Dan Gallagher and Amanda Peet as Beth Gallagher. Reviews were mixed, and Paramount+ canceled it after one season.
• Cobweb (2023). She played Carol, the mother of a bullied boy who hears tapping inside his bedroom wall. Samuel Bodin directed the horror film, and Antony Starr co-starred.
• Party Down, season 3 (2023). Scheduling conflicts kept her out of most of the revival. She returned for a surprise cameo in the season finale.

Recent Work (2025 to 2026)

The fetched filmography lists no screen credits for 2024. She returned with a busy 2025.

• Zero Day (2025). Netflix released this six-episode limited series on February 20, 2025. Lesli Linka Glatter directed every episode. Robert De Niro played George Mullen, a former president who leads the inquiry into a deadly cyberattack.

Final Thoughts

Lizzy Caplan built her career one step at a time. Guest spots led to sitcom leads. A cult comedy led to a cable drama. That drama led to a run of limited series in which she often plays the most watchful person in the room. Few actors move as easily between a catering comedy, a 1950s research lab, and a Stephen King town.

Her record also shows patience. Several of her early series lasted only one season. She kept taking interesting parts, and the larger roles came in her thirties. With a festival film waiting for release and a lead in a Noah Hawley series ahead, the next phase looks as varied as the last one.
