I Love You, Man (2009)

Description: Peter Klaven (Paul Rudd, Knocked Up The 40 Year Old Virgin) is a successful real estate agent who, upon getting engaged to the woman of his dreams, Zooey, (The Office's Rashida Jones), discovers, to his dismay and chagrin, that he has no male friend close enough to serve as his Best Man. Peter immediately sets out to rectify the situation, embarking on a series of bizarre and awkward man-dates, before meeting Sydney Fife (Jason Segel, Forgetting Sarah Marshall), a charming, opinionated man with whom he instantly bonds. But the closer the two men get, the more Peter's relationship with Zooey suffers, ultimately forcing him to choose between his fiancee and his new found bro, in a story that comically explores what it truly means to be a friend.
