What's Up, Doc? is a Looney Tunes cartoon film directed by Robert McKimson and produced by Warner Bros. Cartoons. It was released by Warner Bros. Pictures in 1950 to celebrate Bugs Bunny's 10th birthday that year, in which he recounts his life story to a reporter from the "Disassociated Press". Bugs talks about his birth, his rise to fame, the slow years, and how famous Vaudeville performer Elmer Fudd chooses him to be part of his act. Eventually the duo comes upon their classic formula of Hunter vs. Hare. The short also was the first (since The Unruly Hare) to use the title card music which would continue to be used in Bugs Bunny's cartoons and in most modern Looney Tunes series (such as being an end credits theme for The Looney Tunes Show and Looney Tunes Cartoons). Arthur Q. Bryan, Dave Barry and The Sportsmen Quartet performed voice works but were not credited.
