'''''40 Days and 40 Nights''''' is a 2002 film directed by Michael Lehmann, written by Rob Perez and starring Creator/JoshHartnett, Shannyn Sossamon, Paulo Costanzo and Vinessa Shaw.

Matt Sullivan (Hartnett), after a bad breakup and finding out his ex-girlfriend Nicole (Shaw) is now engaged to be married to another man, decides to give something up for Lent: namely, [[CelibateHero any form of sex]], including [[ADateWithRosiePalms keeping himself company]]. When his friends find out, they make a SideBet that he won't make it, which eventually goes viral with people online betting on what day and act he'll break the vow to. Things go a bit awry when he meets Erica (Sossamon), the girl of his dreams, soon after.
