40 Days and 40 Nights stars Josh Hartnett as Matt, a Web designer who gives up screwing for Lent. The Catholic League isn't happy that the semiautobiographical script by Rob Perez uses the period of Lenten fast to set up a one-joke sex farce. It doesn't help that Matt begins his crusade by winking at a crucifix and saying, "Dude." After Matt meets a hottie, Erica (Shannyn Sossamon), his friends take bets on how long he can collect bodily fluids without shooting the works. Yup, director Michael Lehmann, far from the glory days of Heathers, has made a movie about a hard-on, in which he relentlessly pounds a flaccid premise.

“I'm Yours”

Jason Mraz re-emerged after his disappointing second album with this lead single, a Jack Johnson-esque ditty about giving yourself fully to someone else. The success of the reggae-tinged song (it earned two Grammy nods and a spot on the Billboard singles chart for well over a year) was something the folk-pop singer never predicted when he wrote it in 15 minutes at home. "I played a happy-hippie chord progression that would probably work without 50 different Bob Marley songs," he told Rolling Stone. "I thought, 'It's too novelty. This is a nursery rhyme,'" concluding that "you can never guess what's gonna be a hit."
