What's Up, Doc?

What's Up, Doc? retells Bugs Bunny's climb from baby performer to headline act through a rapid-fire series of musical numbers and visual jokes. The short is staged like a mock biography, hopping from babyhood gags to vaudeville sets and screen parodies while Bugs slips into impressions of well known entertainers. Elmer Fudd appears as a recurring foil and joins Bugs for a performance of the title song, turning their rivalry into part of the show. The cartoon leans on music, impersonation and slapstick more than plot, so scenes move fast and punchlines come thick, keeping the focus on performance rather than surprise developments. Its animation and pacing broadly reflect the studio's theatrical cartoon style of the period, with quick edits.

Directed by Robert McKimson and written by Warren Foster, this 1950 Warner Bros. Looney Tunes short stars Mel Blanc as Bugs Bunny and voices impressions credited to him, with Arthur Q. Bryan and Richard Bickenbach listed in uncredited roles, respectively.

As a theatrical cartoon short it was distributed on Warner theatrical bills, so box office totals weren't tracked the way feature films were. Its exposure came from repeated runs in cinemas and later television syndication rather than a commercial gross.

By leaning on vaudeville routines and celebrity impersonations, the cartoon reinforced Bugs Bunny's image as a quick-witted showman. Its impersonations of figures like Al Jolson and Eddie Cantor highlight how Looney Tunes used popular entertainment references, helping make Bugs a touchstone in American animation. Vaudeville roots are clearly on display.
