The movie tells about Elwood P. Dowd is a rich bushel who starts seeing visions of a giant rabbit named Harvey. Things seem to get more complicated in front of this man as his family thinks the middle-aged stranger is crazy, but he feels what no one feels.
If you're for warm and gentle whimsey, for a charmingly fanciful farce and for a little touch of pathos anent the fateful evanescence of man's dreams, then the movie version of Harvey is definitely for you.
Henry Koster might not have been the right director for this whimsical fantasy, based on the 1944 Pulitzer Prize-winning play, but Jimmy Stewart and especially Josephine Hull (in an Oscar-winning turn) are superb.
Elwood may be a drunk (or not -- does he ever actually take a drink?), and he may be delusional, but he is also happier, less neurotic, and more content than the so-called normal people who surround him and claim to be looking out for his best interests.
Unhappily, what the film also borrows from the play, and somehow makes more conspicuous, is a tendency to drag its feet for long stretches, especially during the virtually actionless last third of the story.
