Jon Favreau (Swingers) was looking to direct a John Carter of Mars movie, but Paramount decided to shelve the whole thing:
Unfortunately, due to the 2008 Paramount production of Star Trek, it looks like Carter is not going to happen in the near future. I assure you that the script and artwork were very well received, but they’ve got a lot of “similar” stuff in the pipeline at the studio. I am trying to help position the film to get made and remain committed to seeing it through. That said, it’s not going to happen this year.
