The newest squad of Marvel movie superheroes has been assembled now that Fox has finally picked its cast quartet for "The Fantastic Four," and, as one should probably come to expect in today's climate of insta-feedback, the fan reactions are very split at the outset.

As long suspected, "Fruitvale Station" and "Friday Night Lights" actor Michael B. Jordan will become Johnny Storm, "The Human Torch" for the pic, re-teaming with his "Chronicle" director Josh Trank for the project. After months of speculation and tongue-in-cheek responses to the rumor, this is not surprising — or news, really.

However, the three add-ons that join Trank's team of cosmic radiation-exposed astronauts do come as a bit of a jolt. According to Variety, Kate Mara ("House of Cards") joins the fold as Johnny's sister Sue Storm, aka the Invisible Woman. No details have yet emerged as to how that relationship will be presented in the reboot, though many suspect adoption or half-parentage will come into play.

Meanwhile, Miles Teller — who recently starred with Jordan in the bromantic comedy "That Awkward Moment" and will re-team with him again for a new heist flick by director Tom Gormican — comes in as Reid "Mr. Fantastic" Richards, a scientific genius who acts as a father figure for the group. Despite his ability to stretch and twist his body every which way, Richards is a relatively subdued guy. (Note: There's talk that Teller's "Divergent" series obligations might render a kink in his "Fantastic" involvement, though.)

Finally, Ben Grimm, aka The Thing, reportedly will be portrayed by Jamie Bell ("Billy Elliot"). His is a character filled with self-loathing and anger over his monstrous, rock-like appearance, and Bell's experience with motion-capture performance in Steven Spielberg's "The Adventures of Tintin" might just be a weighty feather in his cap for snagging this role.
