This is a looong shot.
All I remember about the animated clip is a giant gorilla (possibly a robot gorilla) who wants to be an actor. He’s cast in a movie about a bunch of boy scouts (which looks ridiculous, 'cause the other characters are played by actual cartoon boys).
This may be a Harvey Birdman-type thing where he is an actual character from a serious cartoon put into a funny situation. It’s not a whole series about the gorilla, just a story thread, maybe even for one episode. He may not even be a gorilla. Maybe a robot. Or robot gorilla. or something else.
Anyway, very funny. Something on Adult Swim, maybe? I’m going craaaazy.
