A friend (you know who you are) sent me this link. Apparently there's a live-action “Fat Albert” movie under production.
I think any attempt to convert any successful funny cartoon (not the super-hero stuff, but comic cartoons) is ill-fated and should not be pursued. I might be wrong here, but my quick mental list of comic cartoons that have been made into live-action movies (Flintsones? Scooby-Doo?) consists of flops.
I'm willing to be proven wrong on my assertion that all such past endeavors have been flops. Drop me a comment if you've got an example of a non-flop comedic-cartoon-as-live-action-movie.
