Arsenic and Old Lace. This movie is very funny. I love the insanity of all the characters, and the general story of old ladies hiding bodies in their basement and the nephew trying to keep the police and his girlfriend from finding out. Cary Grant has always been one of my favorite actors (though I generally don't like pretty boys in movies), and all the other actors were excellent character actors. I will never get the scenes of the bugle charges up the stairs, by the uncle who thinks he's Teddy Roosevelt, out of my memory.
