As Aaron Allston notes: there is going to be a Marmaduke movie,but not… well, read:
Calvin & Hobbes. If there’s one comic strip just about everyone wishes hadn’t stopped, it was Bill Waterson’s epic about a boy terror and his imaginary(?) friend, a stuffed tiger. They should have hucked “Dennis the Menace” when looking to the funnies and picked up Calvin, but… How it would work: Give it to Pixar and let them work on it without interference. Send Waterson to them in a locked crate so they can study him at leisure. If anyone tried making this in to a live-action film, it would fail so hard that audiences would be killed by the shrapnel.
When you think about it, the fact that there isn’t a Calvin & Hobbes film out there is superficially inexplicable. The combination of nigh-universal audience appeal + actors/actresses fighting to get in on the project + major animation studio capable of handling it should = instant box office mega-mojo. That it doesn’t… oh. Right. That entire ‘eating your soul’ thing that happens to movie executives above a certain level.
