The Best Man (1999)

Harper's autobiographical novel is almost out, his girlfriend Robin desires commitment, and he's best man at the wedding of Lance, a pro athlete. He goes to New York early (Robin will come for the wedding) to hang out with Lance and other friends, including Jordan, his former almost-lover, now in media and privy to an advance copy of the book. The men discuss women, never facing their own double standard; Jordan wants to try again with Harper, at least for one night; and Harper fears that Lance will read his book and learn that the bride-to-be slept with him once to avenge Lance's many affairs. Can Harper mature before Lance kills him, Jordan seduces him, and he loses Robin?
