The Lorenzo Music, Bill Murray Connection

In the Biography for Bill Murray (I), there's a trivia section, but this one is the neatest one of all:
"Shares two characters with the late Lorenzo Music. He played Peter Venkman in the film Ghost Busters (1984), while Lorenzo played Venkman in the animated series, "Real Ghost Busters, The" (1986). Lorenzo was also the voice of Garfield in numerous cartoons, while Bill provides Garfield's voice in Garfield: The Movie (2004)."
So I guess that's why the voice of Garfield in the new movie isn't played by the same voice of Garfield in the TV Show. The guy is dead. Bill Murray, though, is a good replacement.
