Do you know whether Harvey is a 6foot white bear or rabbit i can`t remember?

Harvey is a 1950 film based on Mary Chase's Pulitzer Prize-winning play of the same name, directed by Henry Koster, and starring James Stewart and Josephine Hull. The story is about a man whose best friend is a "pooka" named Harvey—in the form of a six-foot, three and one half-inch-tall rabbit.
