Elwood P. Dowd first walked onto a Broadway stage at the 48th Street Theatre on November 1, 1944.
Elwood is a good-natured soul who has a friend no one can see – a six-foot, three-and-one-half-inch tall rabbit named Harvey, the titular character in the play by Mary Chase. A film version in 1950 featured James Stewart as Elwood.
Elwood, being outgoing and a perfect gentleman, naturally introduces Harvey to everyone he meets. His sister, Veta, increasingly finds his eccentric behavior embarrassing to her and her daughter Myrtle Mae’s would-be social status. Six foot rabbits are not particularly welcome among the country club set (and since he’s invisible, no telling what color he is). Veta decides to send Elwood packing to a sanitarium to solve the giant rabbit problem, setting in motion a comedy of errors instead.
Actually, according to Elwood, Harvey is a pooka, a deft shapeshifter, able to assume a variety of forms – dog, horse, goat, goblin, and of course rabbit. These forms may be pleasing or terrifying. A good pooka is a benevolent creature with the power of human speech, able to give sound advice and steer you away from evil. The bad pooka, on the other hand, is a blood-thirsty, Donald Trump-like creature who’d just as soon eat you as look at you. Harvey is presumably the former.
Doctors plan to give Elwood a serum that will stop him from “seeing the rabbit.” As they prepare for the injection, Veta is told by their cab driver about all the other people he has driven to the sanatorium to receive the same medicine, warning her that Elwood will become “just a normal human being. And you know what bastards they are (stinkers, in the movie).” Veta has a change of heart and halts the procedure after which Veta and Myrtle Mae, Elwood and Harvey all ride off on the bunny trail into the sunset.
