Harvey

Elwood P. Dowd (Stewart) is a middle-aged, amiable though somewhat eccentric man whose best friend is an invisible 6’ 3½" tall rabbit named Harvey. As described by Dowd, Harvey is a pooka, a benign but mischievous creature from Celtic mythology who is especially fond of social outcasts (like Elwood). Elwood has driven his sister and niece (who live with him and crave normality and a place in society) to distraction by introducing everyone he meets to his friend, Harvey.
