There were many, many attempts to bring the "John Carter of Mars" series to screen. We've already seen concept art for the Disney movie John Carter coming out this year. Plus, we've seen concept art from the film when Robert Rodriguez was supposed to direct.
Looking Glass Films has a video by Kerry Conrad, the creator of the visually stunning Sky Captain and the World of Tomorrow. It was found by the massive John Carter fan site Barsoomia.com. The production predates the 2012 version by several years.
The promo reel is gorgeous and expertly put together. The concept art really captures the feel of a moving and emotional action film while the voice-overs help to explain the images without being obvious.
Update: A YouTube commenter identified the artists as Ian McCaig and Ryan Church. I see one more style in there, but don't know who.
Some (unfortunately low-resolution) screencaps are below. I have no idea who the concept artist is, but the colors and style is exceptionally well-done. There are shades of Avatar with the six-legged horses and other designs, but Cameron stole the ideas from John Carter first. Check it out after the jump...
The video also has test reels including CGI battle scenes and an awesome fight between Carter and a six-armed Barsoomian.
With all the budget trouble their having with the new film we have to wonder what the budget of this film would have been.

What do you think of the concept art?
