While working on Alias, Garner gained a cameo role in Catch Me if You Can (2002), followed by a praised leading performance in the romantic comedy film 13 Going on 30 (2004).
Garner has appeared in supporting as well as lead film roles, including the superhero films Daredevil (2003) and Elektra (2005), the comedy-drama Juno (2007), and the fantasy comedy The Invention of Lying (2009).

Critical reception towards the film was mixed and Mick La Salle of The San Francisco Chronicle describing her part, remarked: "It's not much of a role, but she's perfectly nice in it.
While the film received lukewarm reviews, it grossed US2.2 million worldwide.
