Ellen Muth

Muth was born in Milford, Connecticut, to Eric (a military veteran) and Rachel Muth.

As of 2004, Muth was a member of Intertel and Mensa, high-IQ societies. She attended the Skip Barber Racing School and the Lee Strasberg Theatre and Film Institute.After a brief stint as a model with Ford Models and Rascal's Agency, Muth pursued a career in acting, studying at the Lee Strasberg Theatre and Film Institute in New York City, and getting her first professional experience doing commercials in 1993. Her first major role was in the 1995 film Dolores Claiborne. She followed that with a role in the eighth-season premiere of Law & Order.

Muth's appearance as the daughter in the 1999 film The Young Girl and the Monsoon earned praise from Stephen Holden of The New York Times for her range in portraying a character "who one minute can be as clinging as a baby and the next delights in cruelly demolishing the nearest grownup with laser-like sarcasm" and her chemistry "whenever Constance (who narrates the film) is on the screen with her father Hank (Terry Kinney)".

Her 2000 work included appearances in episodes of The Beat and Law & Order: Special Victims Unit, as well as a role in The American Collection adaptation of "Cora Unashamed", a short story by Langston Hughes from his 1934 collection The Ways of White Folks. Muth also had a guest role in "Don't Ask", the original unaired pilot episode of the 2000 Fox show that eventually aired as Normal, Ohio. The show's revamp eliminated her role. That year, Muth played the lead in the Lifetime Original Movie The Truth About Jane about a high school girl's struggle with her sexuality and acceptance.

Muth starred in the 2003–04 Showtime television series Dead Like Me in the role of Georgia "George" Lass, the protagonist and one of a team of grim reapers.

Muth's next roles were lower in profile. She appeared in Jack 'n' Jill, a 2007 MFA thesis film. She voiced the character of Addie Vost in the first animated short of Tofu the Vegan Zombie and a character in the audio dramatization "Anne Manx in the Empress Blair Project". In September 2008 she joined three other actors at the Theatre Artist Workshop in Norwalk, Connecticut, in a reading of Fleece the Flock, an original musical comedy in development and directed by Joel Vig.

After some delay, Dead Like Me: Life After Death, a film directed by Stephen Herek based on Dead Like Me and featuring many members of the show's cast, including Muth, was released direct-to-video in March 2009.

In 2012, Muth returned to the big screen in the romantic comedy Margarine Wars alongside Robert Loggia and Doris Roberts. The film debuted in Los Angeles on March 29, 2012.

In 2013, Muth made a guest appearance in two episodes of the first season of the TV series Hannibal, produced by Bryan Fuller, the creator of Dead Like Me.
