Christine Taylor has joined the cast of the new comedy, License to Wed for Warner Bros. Pictures and Village Roadshow Pictures.

Robin Williams, Mandy Moore and John Krasinski have already signed on to the film. The Hollywood Reporter says the story revolves around a young couple (Moore and Krasinski) whose wedding plans are interrupted when the pushy minister (Williams) of the bride's family church orders the pair to complete a marriage preparation course. They must pass the class if they want to marry in his church. Taylor will play Moore's older sister.

Vince DiMeglio and Tim Rasmussen completed the rewrite of the Kim Barker and Elizabeth Chandler (The Sisterhood of the Traveling Pants) script; Ken Kwapis is directing. License to Wed will start production next month.
