“Harvey” is a 1950 drama based on the play of the same name written by Mary Chase. It was directed by Henry Koster, and it stars James Stewart as a middle aged eccentric whose best friend is an imaginary six foot high rabbit named Harvey. Elwood P. Dowd is an eccentric middle aged man with a propensity towards alcohol. He is an amiable, friendly man with an everlasting sunny disposition, and he believes that his best friend is a tall rabbit whom Elwood describes a s a pooka, a Celtic mythical creature which befriends outcasts and misfits. His kooky antics are a great source of grievance for his sister Veta, who goes out of her way to have Elwood put into a sanatorium. Eventually she succeeds and has Elwood put under the care of Dr. Lyman Sanderson. Dr. Chumley, the head of the sanatorium, takes special interest in Elwood. Despite the fact that one of them is a respected psychiatrist and the other a grown man with a gigantic rabbit for his best friend, Elwood grows on Dr. Chumley. The psychiatrist is impressed with Elwood’s eccentric, yet endlessly optimistic and good natured views on life, and soon he is drawn into Elwood’s bizarre world, not only believing that Harvey is real, but also talking to him on regular bases. In the meantime, Dr. Sanderson has convinced Elwood to receive an injection of a serum called Formula 977, which will put an end to his delusions. Realizing that she would actually miss Elwood’s eccentricities, Veta runs to the hospital to prevent him from receiving the injection.
