Years ago my mother used to say to me, she'd say, "In this world, Elwood, you must be" — she always called me Elwood — "In this world, Elwood, you must be oh so smart or oh so pleasant." Well, for years I was smart. I recommend pleasant. You may quote me.
We could all envy Elwood P. Dowd, a softspoken dreamer of independent means who has a marvelous, magical friend named Harvey. Jimmy Stewart is at his best in this comic fantasy, ably supported by Josephine Hull as his sister Veta - a Thurber caricature come to life - and a slew of other fine character actors. Do watch it if you can find it - it will surely make you laugh and give your spirits a lift.
