Donnie Darko (2001)
Stars: Jake Gyllenhaal, Jena Malone
You cannot overestimate the Jake Gyllenhaal mojo. He's a turn-on. This is a fact. Add to that the allure of the high school outsider, the logistical difficulties of time travel, and the knowledge that Donnie is gonna die (spoiler alert? sorry), and you have a potent message: Have. Sex. Now.
