Harvey Party Universal movie studio hosted a party with Jimmy Stewart and Harvey, where Jimmy plays a lovable tippler "Elwood P. Dowd" who pals around with a six and three-quarter foot tall invisible rabbit named Harvey. And he's a pooka, in old Celtic mythology a fairy spirt in animal form. Some of the movie stars bring their children to visit Harvey, Donald O'Connor and his family and other stars and their families. The children seem to be enjoying themselves.
