So here's the thing...
You know what I'm talking about: John Carter of Earth is magically transported to
But, sadly, I'm enough of a geek to want to make a couple of quick observations based on the trailers I'm seeing:
(1) Lower gravity, especially on the scale they seem to be implying, would potentially mean lower atmospheric pressure. So, unless the atmosphere of
(2) Lower gravity means a reduction in weight but not in mass. This reduces the energy requirements to move objects in that you don't have to fight another vector of acceleration (i.e. gravity) but a bigass piece of rock in free fall is still hard to move even if you're not fighting gravity.
(3) Rephrasing point (2) above, lower gravity does not mean reduced inertia. Once you get that bigass piece of rock moving, it's gonna be difficult to stop it again. Just, you know, be sure to plan ahead.
(4) With less gravity your feet also have less friction, which in turn makes it more difficult to walk or, less prosaically, swing giant boulders around with an attached chain. Maybe try wearing some big, rubber-tread shoes? Maybe cleats? Ah, you'll think of something.
(5) We all knew the depiction of Dejah Thoris was gonna be tricky, but it just amuses me that for once a female character in a summer action flick will almost certainly be wearing clothing MORE OFTEN in the movie than in the book.
* Maybe also because he was a white dude and, let's face it, when the author was writing it was pretty much assumed that white dudes were better than everyone else.
** Yeah, that's a major exaggeration, but anoxia is still no joke.
