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)".[9]
Muth's next roles were lower in profile. She appeared in Jack 'n' Jill, a 2007 MFA thesis film.[12] She voiced the character of Addie Vost in the first animated short of Tofu the Vegan Zombie[13] and a character in the audio dramatization "Anne Manx in the Empress Blair Project".[14] 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.[15]
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.[17]
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.[18][19]
In 2004, Muth's work on Dead Like Me received two nominations: for a Saturn Award in the Best Actress in a Television Series category and for a Satellite Award in the category of Best Performance by an Actress in a Drama series.
Muth has withdrawn from public life since her 2013 appearances on Hannibal, instead concentrating on a coffee business she launched and a cat-breeding business as of the early 2020s. Saying she eventually wanted "to settle down and have a family of my own", Muth told a relaxed-lifestyle website in December 2015 that she had "hit the pause button on the acting for now."[22]
