Yeah he voices Garfield as well as Fred from Scooby Doo. I think he may have voiced Scooby at some point as well. But yeah it’s impressive. I think he also did Ray and Slimer from the cartoon The Real Ghostbusters.
Also did you know that Peter Cullen voices Eeyore (not sure how to spell it lol) from Winnie the Pooh?
I really get excited about actors and actresses lol I often drive my parents and sis crazy by going “OH OH THAT’S SO AND SO!!” or “OH HE VOICES BLAH BLAH” when we saw the 2nd Night at the Museum movie and saw the Tuskegee Airmen I instantly recognized one of them and started pointing and going “THAT’S THE PONTIAC BANDIT! THAT’S DOUG JUDY!” Every time he appeared on screen.
Also remember how I mentioned Frank Welker voices Garfield? Well Odie is voiced by the dude who originally voiced Grimlock Gregg Berger.
