Speaking of Michael Keaton - One of my favorite funniest is Dream Team.
I’ve never seen that. I will check it out.
Another great movie with Dom DeLuise as the king of all mental patients is “The End” starring Burt Reynolds, Joanne Woodward, Kristy McNichol, Robby Benson, and Sally Field. Myrna Loy plays Burt’s mom! My parents let us kids watch that one. (I marvel at how my sense of humor was formed.) Of course, you used to get these movies semi-expurgated on tv; those days are over.
