It's certainly not common unless it's a well-established classic, like The Wizard of Oz, A Christmas Carol, Treasure Island, etc. Those have been around long enough to merit a number of representations that aren't based on mass-media. Nonetheless, they tend to be specialty figures and not very common. You'll probably end up waiting for the movie to come out. I mean heck, I was waiting for a good Faramir figure since I was twelve, but then the movie came out and I got my wish. There is always hope!
