Though, I agree with Perineum Falcon, that it could be quite fun to see Tintin and Snowy on big screen again,Aazealh said:
it's quite sad that Spielberg and others disregard Hergé's wish - Tintin not being handled by another author that is. I would prefer if they honored his expressed desire.
But, to jump onto the nostalgia train: Warner Bros smells money and is planning to turn some Hanna-Barbera cartoons into big screen adaptions. Those include: the Jetsons, Yogi Bear, Tom & Jerry
Latter is going to be an origin story about how the two met each other, their rivalship, etc.
And of course, mouse and cat are CG characters in live-action setting.
