It's a Catch-22, I think. On one hand, the animated specials and movies have left a pretty big imprint on pop culture, but they've also undoubtedly driven more people to the strip than would normally have read it.
When I was learning to read, I wore out a copy of the
Peanuts Treasury, but I'm sure I saw the animated specials first, like most kids.
Calvin and Hobbes is unique in that its popularity is so huge despite never being animated. I'm sure a movie would only make its stamp in the public consciousness even larger, but fortunately, it seems like that doesn't matter very much to Watterson.
Of course I'd be curious to see one, but it'd make me a bit sad, too, for some reason. An actor might do a fine job voicing Hobbes, but it'd still be odd. And I wouldn't want that voice to become associated with the character's voice in my head, if that makes sense. Like the way Lorenzo Music's voice became so associated with Garfield. Fortunately, that doesn't matter to me so much, since
Garfield has never really had anything to say.
I'm reminded of the Opus special,
A Wish for Wings That Work. After years of reading
Bloom County,
Opus's voice sounded weird and kind of wrong, even though Michael Bell's performance was fine and even matched the character. But it still seemed weird.
I liked the special, but it still feels to me like an alternate universe's Opus.
