Rabbit of Seville is a 1949 Warner Bros. Looney Tunes theatrical cartoon short released in 1950. It was directed by Chuck Jones and written by Michael Maltese.
The cartoon, in a plotline reminiscent of Stage Door Cartoon, features Bugs Bunny being chased by Elmer Fudd into the stage door of the Hollywood Bowl, whereupon Bugs tricks Elmer into going onstage, and participating in a break-neck operatic production of their chase punctuated with gags and accompanied by musical arrangements by Carl Stalling, focusing on Rossini's overture to The Barber of Seville.
Stalling's arrangement is remarkable in that the overture's basic structure is kept relatively intact; some repeated passages are removed and the overall piece is conducted at a faster tempo to accommodate the cartoon's standard running length. In 1994 it was voted #12 of the 50 Greatest Cartoons of all time by members of the animation field. The cartoon is available on Disc 1 of the Looney Tunes Golden Collection: Volume 1.
