Hey, not all wedding movies have to be chick flicks. Take 2009’s “The Hangover,” which tells the story of three crazy groomsmen (Bradley Cooper, Zach Galifianakis, and Ed Helms) who literally lose their groom (Justin Bartha) after a crazy night of partying in Vegas. Hilarity ensues as the groomsmen realize that the only way to find the groom and save his wedding is to re-trace their night, of which none of them have any memory. Plus, there’s a Mike Tyson cameo! Cool!
