But a composite of scenes which are unchanged in the final cut (apart from sound) would be ace ... help you appreciate Jim Carrey and - well, Cameron Diaz - at their very finest.
I enjoyed most seeeing the "Mask dog" running around as a regular dog.
Sad that 10+ years later both Carrey and Diaz are not a positive thing to have in a film.
Richard Jeni is a weird part of this ... In any other film he'd be the "comic buddy" to the straight-man lead actor. And he's clearly trying to be. Except that the "straight leading man" is Jim Carrey, who's funny, and he isn't.
Wacky!
Somewhere on VHS I've got a thing about the making of the Mask cartoon, which starred Rob Paulsen. A low-budget affair, that cartoon, but I watched it.
