Harvey
That six-foot-three-and-a-half-inch white rabbit from the 1944 comedy Harvey still has a lot to say some 70 years later. Not literally, because of course we never see or hear from the title character of Mary Chase's Pulitzer Prize-winning play, but spend a couple of hours in the company of Jim Parsons's Elwood P. Dowd, who claims Harvey is his best friend, and you won't doubt his existence.
