3. "Fantastic Four" (Release Date - August 7)

Jordan is giving his own take of The Human Torch.

Unlike some of its superhero-themed contemporaries, Joshua Trank's "Fantastic Four" reboot is said to be a "hard sci-fi" flick. Trank himself recognized this when he said, "I would say that the science fiction of it is a big thing that sets it apart from most of the other superhero genre films," as per Newsarama.com.

Trank even added, "I'm a huge David Cronenberg fan, and I always viewed Fantastic Four and the kind of weirdness that happens to these characters and how they're transformed to really fall in line more with a Cronenberg-ian science fiction tale of something horrible happening to your body and [it] transforming out of control. And the potential for a hard sci-fi take on that material makes me really excited."
