I know this thread is in the correct forum 'cause Jack Briggs said this is the place to discuss Actors & Actresses. Cheetah (world's oldest chimp), Trigger (born: White Cloud) and Lassie (the Dog....no, really, that's her name, "Lassie the Dog") are all listed in the IMDB. Here's something interesting, Lassie (T.D.) was over 40 years old when she started the TV series in 1954! That's right, her first credit was in a 1911 project. I have more research to do, I need to look up Willie the Killer Whale, Maltese Falcon and Nemo.
