Joe Alaskey, one of the actors who succeeded the legendary Mel Blanc as the voice of Bugs Bunny and Daffy Duck, passed away Wednesday at age 63. CNN reports he had been battling cancer.

The second actor to play Grandpa Lou Pickles on "Rugrats," Alaskey also provided the voices of Tweety Bird, Sylvester the Cat and Plucky Duck. He won an Emmy in 2004 for his work as the title character in Cartoon Network's "Duck Dodgers."

His work extended beyond animation, however, to video games and live-action film. Alaskey provided the voices of President Nixon in "Forrest Gump" and Stinkie in "Casper." He also narrated Investigation Discover's 2014 series "Murder Comes to Town," and impersonated Jackie Gleason's voice to help repair the audio on "lost" episodes of "The Honeymooners."

Recalling working with Alaskey on "The Garfield Show," Mark Evanier wrote on his blog, "The only problem we had was that Joe had so many different voices that it was sometimes difficult to choose which one we wanted out of him. The one I liked best was when he sounded like Joe Alaskey. He had a long, long list of voices but that's the one I will miss the most."
