Garfield and Gadget! I used to watch those all the time, too. They were great. I watched Heathcliff too, when I could. It was only on a station that we could barely receive, so some days it was watchable and others it was just static.
Garfield, TMNT, and Inspector Gadget, I know have both been made into big screen movies. Any others?
There was a George of the Jungle movie (maybe 2) and I think a Dudley Doo-Right movie as well. They aren't quite as recent, but also not too old.
The Garfield movies were great. I really should watch them again sometime soon.
TMNT was good, but the style of the CGI characters took some getting used to. Gadget was so-so. It wasn't bad, but it didn't have as much in common with the cartoon as I would have liked.
I've seen trailers for an Alvin and the Chipmunks movie that is coming up. That's the next cartoon->movie revival I know about.
