Will Ferrell, 'Stranger Than Fiction'

Ferrell plays IRS agent Harold Crick, who must audit lefty bakery owner Maggie Gyllenhaal. "Crick was a man of infinite numbers, endless calculations, and remarkably few words," says the film's narrator, a book writer whose voice Crick hears in his head.
Best tax line: (From a Crick colleague) "Dude, I just totally caught some insurance adjuster claiming his jet ski as a work vehicle."
Tax takeaway: Even badly socialized obsessive-compulsive tax agents can loosen up and get the girl in the end.
