Robin Williams is ready to return to the priesthood, as the "License to Wed" star is set to play Father Monaghan in Justin Zackham's star-studded comedy "
The Big Wedding."
De Niro and Keaton will play a long-divorced couple who, for the sake of their adopted son's wedding and his very religious biological mother, pretend they're still married. They quickly learn that acting the part isn't easy, especially when their past, present and future unravel for all to see.
