Clearly "Princess of Mars" is The Asylum's cash in on the "John Carter" movie that was out in March 2009, as "Princess of Mars" came out in December of the very same year. Is that a trademark of The Asylum, to take something that others made famous and then just sponge and leech of that success?
At any rate, and regarding the motivation behind this movie, then The Asylum actually managed to pull of a fairly decent movie here, compared to some of the other more questionable releases they have spewed out.
The story, if you are familiar with either the "John Carter" movie or the E.R. Burroughs novel, is about John Carter, a man from Earth, who end up on a distant red planet, where he have to save their world from impending doom.
Pretty straight off the copy and paste storyboard here, without anything new or overly interesting to be added to the story. But still, the movie was enjoyable for what it was. A word of warning though; if you have seen the "John Carter" movie that was out earlier in 2009, then chances are that you might want to stay clear of this version. Imagine a weird hybrid of the 1980's "Flash Gordon" movie mixed with Disney's "John Carter" movie, and you have the end result coming out as "Princess of Mars".
One thing that did puzzle me, though, with the technology and resources available to the human-like race on this red planet, why would their princess be clad so scantily like a common... Well, you get my meaning. It just didn't make sense. Or did it? Well, you have Traci Lords in the role as the princess, so of course, why wouldn't the director be having her running around half naked?
The creature effects were adequate to look at, except for those bipedal reptiles that they used for mounts. They were just horrible to look at. Awfully animated CGI and they walked like they all had bad indigestion.
I will say that The Asylum did put out a fairly enjoyable Sci-Fi movie here, but in the wake of Disney's "John Carter", then the movie pales in comparison.
