In "I Love You, Man", the new comedy from co-writer/director John Hamburg ("Along Came Polly"), Peter Klaven (Paul Rudd) is a successful real estate agent who, upon getting engaged to the woman of his dreams, Zooey, (Rashida Jones) discovers to his dismay that he has no male friend close enough to serve as his Best Man.

Peter immediately embarks on a series of bizarre and awkward "man-dates" to find such a friend, before meeting Sydney Fife (Jason Segel), a fun-loving, charismatic man - just Peter’s opposite - 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 fiance and his newfound "bro," in a story that comically explores what’s at the core of male friendship and what it truly means to be a friend.
