Williams and Billy Crystal co-star in this comedy about two men—playing Dale Putley and Jack Lawrence—in search of a runaway teenager. Their girlfriend of 17 years past tells them both that they are the boy’s father, in hopes that at least one of them will find the boy. Director Ivan Reitman says about the two stars:
I always wished that Father’s Day turned out better. We didn’t quite get it right and I always sort of felt responsible and guilty about not doing a better job for the two of them because they’re so brilliant.
