Los Supersónicos conocen a los Picapiedra

In this movie, two great Hanna-Barbera families are thrown together when Elroy Jetson accidently time warps his family to the Stone Age. Personally, I like George Jetson. He's funny, so it's easy for me to feel for him when he puts up with Mr. Spacely and the time warp. Mel Blanc can also prove he's capable of playing selfish people, but Mr. Spacely wasn't his best performance. I like Dino better.
