What's Up, Doc?: Celebrating 60 Years of Looney Tunes

What's Up, Doc?: Celebrating 60 Years of Looney Tunes is a 1990 television special that aired on CBS on February 15th, 1990, commemorating the 60th anniversary of the Looney Tunes cartoon shorts. The special sees Bugs Bunny, Daffy Duck, and the other Looney Tunes characters take over the Warner Bros. lot and cause all kind of chaos throughout the studio as part of their big celebration. This special was the last to feature the voice of Mel Blanc as the Looney Tunes characters in new material; as Blanc died during production, several other voice actors filled in for him to complete the special, which was dedicated to his memory ("Warner Bros. dedicates this special to MEL BLANC (1908-1989), who for over 50 years, let the Looney Tunes do the talking. We'll miss you, old friend.")
