Ed Helms (so funny in The Office and The Hangover) plays Tim Lippe, an insurance salesman from a small town in Wisconsin who’s traveling to the big city of Cedar Rapids, Iowa, for the first time for a convention. He ends up sharing a room with two other guys, including a crass blowhard from a rival agency played by John C. Reilly. Their adventures over the next 90 minutes pretty much amount to a Midwest version of The Hangover. But there’s a little more to the funny and sweet Cedar Rapids than that. Tim – who’s having an affair with his seventh-grade teacher (played by Sigourney Weaver) and is stymied by hotel keycards – learns a few things about the outside world during his trip. He gets drunk for the first time. He crashes a gay wedding. He has sex with a married woman (Anne Heche). And he smokes crack. Plus, Helms spends a good chunk of the movie in his underwear.
