Description: Spun-off from ABC's prime time series The Bugs Bunny Show and the CBS Saturday morning series The Road Runner Show. The Bugs Bunny/Road Runner Hour was the most succesful and popular attempt to bring the classic Looney Tunes cartoons to Saturday morning television where they became a mainstay for more than three decades. The series presented popular animated shorts which were originally produced for the silver screen, where they would appear right before a major motion picture, but here they were introduced by new segments as well as new title cards not shown in the original theatrical versions. Also included were Road Runner cartoons originally shown on the The Road Runner Show. Many people who grew up watching this show will most likely remember it by the opening theme "This Is It" performed by Bugs Bunny and Daffy Duck which was shown in black & white when it was created for The Bugs Bunny Show but then shown in color and remodified specifically for this Saturday morning series. In the late '70s The Bugs Bunny/Road Runner Hour eventually became The Bugs Bunny/Road Runner Show when CBS decided to add an additional 30 minutes to each episode.
