My Best Friend's Wedding fans have been saying a little prayer for a sequel since the '90s, and much of the film's cast is in agreement. The romantic comedy premiered in 1997 and follows Julianne (Julia Roberts), a food journalist who realizes she is in love with her best friend Michael (Dermot Mulroney) after he gets engaged to Kimmy (Cameron Diaz). To win Michael over, Julianne spends the week before his wedding trying to break him and Kimmy up. Things take a turn for the more complicated when she brings in her gay BFF George (Rupert Everett) to play her pretend fiancé.
