Avery's 1940 film
A Wild Hare is seen as the first cartoon to truly establish the personality of
Bugs Bunny, after a series of shorts featuring a Daffy Duck-like rabbit directed by
Ben Hardaway, Cal Dalton and Chuck Jones. Avery's Bugs was a super-cool rabbit who was always in control of the situation and who ran rings around his opponents.
A Wild Hare also marks the first pairing of him and bald, meek
Elmer Fudd, a revamp of Avery's
Egghead, a big nosed little fellow who, in turn, was modeled after radio comedian
Joe Penner. It is in
A Wild Hare that Bugs casually walks up to Elmer, who is out "hunting wabbits", and asks him calmly, "What's up, doc?" Audiences reacted positively to the juxtaposition of Bugs' nonchalance and the potentially dangerous situation, and Avery made "What's up, doc?" the rabbit's
catch phrase.
Avery ended up directing only four Bugs Bunny cartoons:
A Wild Hare,
Tortoise Beats Hare,
All This and Rabbit Stew, and
The Heckling Hare. During this period, he also directed a number of one-shot shorts, including
travelogue parodies (
The Isle of Pingo Pongo), fractured
fairy-tales (
The Bear's Tale),
Hollywood caricature films (
Hollywood Steps Out), and cartoons featuring Bugs Bunny clones (
The Crack-Pot Quail).
Avery's tenure at the Schlesinger studio ended in late 1941, when he and the producer quarreled over the ending to
The Heckling Hare. In Avery's original version, Bugs and hunting
dog were to fall off of a cliff
three times, milking the gag to its comic extreme. According to a DVD commentary for the cartoon, historian
Michael Barrier explained that the problem Schlesinger had with the ending was that, just prior to falling off the third time, Bugs and the dog were to turn to the screen, with Bugs saying "Hold on to your hats, folks, here we go again!" This line was known at the time as being associated with a sexual gag from the radio, with which Warner Brothers did not want Bugs associated. Schlesinger intervened (supposedly on orders from
Jack Warner himself), and edited the film so that the characters only fall off the cliff twice (the edited cartoon ends abruptly, after Bugs and the Dog fall through a hole in a cliff and immediately stop short of the ground, saying to the audience, "Heh, fooled you, didn't we?"). An enraged Avery promptly quit the studio, leaving three cartoons he started on but did not complete. They were
Crazy Cruise,
The Cagey Canary and
Aloha Hooey. Bob Clampett picked up where Avery left off, and completed the three cartoons.
