Anyone Remember Edgar Rice-Burroughs "John Carter" Character?

Does anyone remember the "John Carter, Warlord of Mars" character, created by author Edgar Rice Burroughs? It's been a long time since I've heard about the character. In fact, back in the early 1980s there was a comic book about his adventures. I've also read one or two of the novels. Now, Disney studios has made a movie about the character and it's coming out in March 2012. There's a lot of animation in the movie, because the storyline is that Mars is populated with intelligent life that are in the midst of a war.  Here's the clip from the upcoming movie. I'm unsure if I want to see it, even though I enjoyed the comic books! - Rob
