I didn't know anything about it so for anyone in my shoes, here is a plot outline. The story takes place in Brooklyn. It is about Mortimer Brewster (a play critic) and his crazy family. We mostly went to see David, the boy who plays his brother, Teddy. Teddy thinks he is Teddy Roosevelt. Teddy lives with his aunts who are crazy (but you wouldn't know it!) They also have a crazy third brother who shows up.
The play had us laughing from the beginning until the very end. If a theater near you does this play, go see it! I think I am going to rent the movie with Cary Grant!
