We have passed along Fantastic Four casting rumors for nearly a year now.  It seems Fox is very close to finalizing the cast.  THR reports the studio is in the final stages of negotiation with Miles Teller for Mr. Fantastic, Kate Mara for Invisible Girl, Michael B. Jordan for the Human Torch, and Jamie Bell for The Thing.  Bell is the only name we have yet to hear attached to the project, but he's a great addition to a promising young cast.  Mara, nearly 31, is the oldest of the group.  Heck, she's older than director Josh Trank (Chronicle), who just turned 30.  The age range may not match the public conception of the Marvel superhero group, but such a group of fresh voices reassures the reboot will look nothing like Fox's other Fantastic Four attempts.

Fantastic Four is scheduled for release on June 19, 2015.  Hit the jump for background from the comics.

Here is an excerpt from Wikipedia with the character bios from the comics:

  • Mister Fantastic (Reed Richards), a scientific genius, can stretch, twist and re-shape his body to inhuman proportions. Mr. Fantastic serves as the father figure of the group, and is "appropriately pragmatic, authoritative, and dull". Richards blames himself for the failed space mission, particularly because of how the event transformed pilot Ben Grimm.
  • Invisible Girl/Invisible Woman (Susan Storm), Reed Richards' girlfriend (and eventual wife) has the ability to bend and manipulate light to render herself and others invisible. She later develops the ability to generate force fields, which she uses for a variety of defensive and offensive effects.
  • The Human Torch (Johnny Storm), Sue Storm's younger brother, possesses the ability to control fire, allowing him to project fire from his body, as well as the power to fly. This character was loosely based on a Human Torch character published by Marvel's predecessor Timely Comics in the 1940s, an android that could ignite itself. Lee said that when he conceptualized the character, "I thought it was a shame that we didn't have The Human Torch anymore, and this was a good chance to bring him back". Unlike the teen sidekicks that preceded him, the Human Torch in the early stories was "a typical adolescent — brash, rebellious, and affectionately obnoxious." [...]
  • The Thing (Ben Grimm), Reed Richards' college roommate and best friend, has been transformed into a monstrous, craggy humanoid with orange, rock-like skin and super-strength. The Thing is often filled with anger, self-loathing and self-pity over his new existence. He serves as "an uncle figure, a long-term friend of the family with a gruff Brooklyn manner, short temper, and caustic sense of humor". In the original synopsis Lee gave to Kirby, The Thing was intended as "the heavy", but over the years, the character has become "the most lovable group member: honest, direct and free of pretension"
