from critics. Nevertheless, Reel Film Reviews found the film to be an "irreverent, sporadically hilarious romantic comedy that boasts fantastic performances from stars Jason Biggs and Isla Fisher". In the thriller The Lookout (2007), opposite Joseph Gordon-Levitt and Matthew Goode, Fisher played a woman used by a gang leader to seduce a man with lasting mental impairments. Describing on how she took her character, she said: "[I]t was one of those situations where I read the script and thought, 'This is the take. I don't want to play the cliché femme fatale. I don't want to come in and be the woman with the sexual appetite, who wants to take down this man. I want to come in and make her this big beating heart, and innocent —a woman who has no identity, who knows the man she's with, who doesn't have an agenda'.

Budgeted at US$7 million, Definitely, Maybe was a commercial success, grossing US$55.4 million worldwide. Fisher also voiced a professor in a city of microscopic creatures in the computer-animated comedy hit Horton Hears a Who! (2008), featuring Jim Carrey, Steve Carell, Will Arnett, among others. Fisher obtained her first leading film role in the comedy Confessions of a Shopaholic (2009), where she played a college graduate who works as a financial journalist in New York City to support her shopping addiction. She felt "apprehensive" as she took on her first star vehicle, stating: "I was gobsmacked that anyone would give me my own movie. I am eternally bewildered. Every time
