I really enjoyed director Andrew Stanton's John Carter. It was a great movie that just got a lot of bad press and had a terrible marketing campaign. This should have been a huge franchise for Disney, and there should have been multiple sequels, but it's never going to happen at the point. I seriously doubt that anyone will attempt to make another movie based on The Princess of Mars book series, and that's really kind of sad.
During a recent interview with Variety the film's star, Taylor Kitsch, talked about the movie. When asked if the bad press was hard for him, he said,
"I mean, look man, it wasn’t an uplifting experience. My biggest regret would have been if I didn’t do enough personally. If I didn’t give it everything I had. If I hadn’t prepped enough. I don’t have that regret, so that allows me to let go. I still talk to Lynn Collins almost daily. Those relationships that were born won’t be broken by people we never met."
The actor went on to talk about the sequel and how awesome the script was:
I miss the family. I miss Andrew Stanton. I know the second script was fucking awesome. We had to plant a grounding, so we could really take off in the second one. The second one was even more emotionally taxing, which was awesome.
I would have loved to see what that sequel would entail. I can't help but believe that the sequel they were planning would have been even better than the first movie. I'm disappointed that it will never happen. Who knows, maybe a few years down the line someone will make another adaptation.
