Harvey has overcome not only time and space but any objections. Elwood P. Dowd (James Stewart) is a wealthy eccentric living with his sister and niece who enjoys a daily tipple especially when it’s with his best friend, a six foot three and a half inch rabbit, the titular Harvey. And Harvey is invisible, in Elwood’s words, a pooka (a ghost in Celtic mythology). When Elwood’s social-climbing sister Veta (Josephine Hull) tries to have Elwood committed to a sanitarium it’s she who winds up incarcerated after she admits she’s heard so much about the rabbit she sometimes sees him too…. Mary Chase’s hit Broadway play ran for a long time and it gets a delightful treatment here with Hull reprising her role: one of the good visual jokes is her short stature. She has some nice jibes about psychiatry including, That’s all they talk about – sex. Why don’t they get out, take some long walks in the fresh air?! The sanitarium director Dr Chumley (Cecil Kellaway) tries to help Elwood but then he has some experiences with Harvey himself … Chase’s Irish Catholic background helped her conceptualise this invisible helpmate as a kind of friendly ghost and it was one of three of her plays translated to the screen. Delicately handled by director Henry Koster, this was adapted by Oscar Brodney (and an uncredited Myles Connolly) and is perfectly judged between staging and characterisation. Great performances make it an enduring entertainment.
