"They called and asked me to be Spanky the Dog in the Garfield movie and I said, 'No, I don't wanna do that'. And they said, 'Oh, Bill Murray's Garfield,' and I was like, 'Oh, then I definitely wanna do it'. So, I wound up doing a movie that I didn't want to do because you didn't know you were doing that movie... I never actually saw it." Comedian and chat show host Jimmy Kimmel signed on as the voice Garfield's pal after learning Murray was onboard the project. Murray recently confessed he agreed to be in the films because he thought the Coen Brothers were behind them. The screenplay for the 2004 movie and its sequel were actually written by Joel Cohen.
