In this bromance, the cinematic equivalent of a rom-com buddy flick, Paul Rudd plays a recently engaged guy who's got the bride-to-be of his dreams but lacks an all-important significant other when it comes to their pending nuptials: a best man. On a determined hunt for a stranger who will stand up for him, he eventually meets a candidate (Jason Segel) with wedding-party potential. Jaime Pressly, Rashida Jones and Jon Favreau co-star.
