Sword & Planet action on distant worlds of high adventure!
Nice! I wonder if one of those structures could be an incubator? I did notice some stairs, though, and ERB's martians used ramps exclusively ;)

I don't think we can expect slavish devotion to the details in the novels. It will be more along the lines of "inspired by" - but as close as we're likely to ever get in a Hollywood blockbuster.
Actually this looks very close to how I imagined it... though less red, of course. I can't help it, I'm excited for the movie, even if it isn't strictly faithful to the source material.
