Well there's at least one that should be suitable for your children, and that is the new Charlie And The Chocolate Factory film with Johnny Depp, less musical than the Gene Wilder one, more weird (obviously helped by Tim Burton directing and Johnny Depp starring) to apparently fit the book better.
I think you mentioned you'd let Ross watch Star Wars, or perhaps more forced him too, lol, Episode III is out on May 19th, which is just 51 days away
(although it may get a 12 or even 15 rating, the first SW film to get higher than PG)
