One thing I always heard from the begining when I talked about this being a movie - was that the rule is that animated movies don't work unless they're Disney movies for kids. Unless they're family movies.
I don't think any movie I would do would be too serious or serious at all.
I like the Stooges. You know what movie I saw that I sort of discovered late was Jerry Lewis in 'The Nutty Professor'. I really liked that.
I think at the point when they were first starting to talk about a movie, it was a little bit different back then.
