Just by going off the actors being considered alone, it's clear that 20th Century Fox is going in a very different direction with their reboot of The Fantastic Four. The actors who are in contention for Reed Richards (Miles Teller, Kit Harington and Richard Madden) are all in their mid-20s, although the Sue Storm contenders Kate Mara, 30, and Saoirse Ronan, 19, represent a more radical age shift. We already reported this week that testing will begin later this month, but today we have new details about the casting process and the plot, thanks to a recent casting call.

A listing posted at Acting Auditions reveals that casting is under way in Los Angeles, with every role up for grabs except for Johnny Storm, which is being played by Michael B. Jordan. This casting notice seemingly confirms the report from this week that the actor was officially attached, although the studio has not made an official announcement. Production is scheduled to start on February 10 in Baton Rogue, Louisiana, so it seems they need to fill out the cast rather quickly, especially if every role except Johnny Storm is open.

However, the most intriguing part of the casting call is the plot synopsis, which leads us to believe that the story is being adapted from the Ultimate Fantastic Four comic books.

"The Fantastic Four will tell the story of two very young friends, Reed Richards and Ben Grimm. After an event transforms the boys, they find themselves empowered with bizarre new abilities. Reed becomes a scientific genius who can stretch, twist and re-shape his body to inhuman proportions. Ben becomes a monstrous, craggy humanoid with orange, rock-like skin and super strength. However, the two end up being owned by the government and used as weapons. But after they mature, two others with powers come into the picture - Sue Storm 'The Invisible Girl' and Johnny Storm 'The Human Torch.'"

The 2005 superhero adventure Fantastic Four took a much different approach, with the foursome all gaining their abilities at the same time after a cataclysmic accident in space. In the Ultimate Fantastic Four comics, Reed was a child genius who conducted experiments for the government at the age of 11. Both Reed and his childhood friend Ben Grimm got their powers when they were in their 20s, after Reed's teleportation experiment went awry.

What's interesting is that, despite all of the casting rumors over the past few months, we haven't heard one single name mentioned in connection with the Ben Grimm (The Thing) role thus far. Regardless, they better find him soon if they expect production to get started on time.

Josh Trank is directing from a screenplay by Jeremy Slater, which was revised by Simon Kinberg. Do you think 20th Century Fox can pull it off and assemble their Fantastic Four cast in just a few weeks time? Only time will tell.
