Julia Roberts, Dermot Mulroney, Cameron Diaz and Rupert Everett star in MY BEST FRIEND'S WEDDING, a high-spirited romantic comedy that serves up something wild, something new, something touching and something truly hilarious.

Comically crazed and full of devious plans, Jules will do anything to steal him back... except tell him the simple truth.
