Rabbit Fire (1951)

Rabbit Fire is a 1951 Looney Tunes (reissued as a Blue Ribbon Merrie Melodie) cartoon starring Bugs Bunny, Daffy Duck and Elmer Fudd. Directed by Chuck Jones and written by Michael Maltese. The short is notable for being the first film in Jones' "hunting trilogy"—the other two films being Rabbit Seasoning and Duck! Rabbit, Duck!. It is also the first film to feature a feud between Bugs and Daffy. Produced by Edward Selzer for Warner Bros. Cartoons, Inc., the short was released to theaters on May 19, 1951 by Warner Bros. Pictures and is widely considered among Jones' best and most important films. It is also the first film to star both Bugs Bunny and Daffy Duck.
