The script for The Fantastic Four reboot is ready, and Kate Mara and two Game of Thrones stars are already auditioning for major roles in the film.

While Michael B. Jordan is confirmed to star as Johnny Storm, testing for the roles of Reed Richards (Mr. Fantastic) and Sue Storm (the Invisible Woman) will begin at the end of this month.

A source told Variety that writer Simon Kinberg was done with the script rewrite and the pre-production was now in the stages of final casting for the film. Kinberg was expected to "substantially overhaul" the script of the Marvel adaptation.

Miles Teller (The Spectacular Now) and Game of Thrones stars Richard Madden and Kit Harrington will be allegedly fighting it out for the role of Mr. Fantastic while Mara and Saoirse Ronan are auditioning for the part of Sue Storm.

But Teller seemed to have suggested that the role was already his, as when he was questioned about it at the Sundance Film Festival, the actor said that filming would begin soon. "Yeah that should be happening in the next few weeks," he said.

The film is being directed by Josh Trank (Chronicle),  and produced by Kinberg, Matthew Vaughn and Gregory Goodman.

Teller also told MTV that he was very keen on taking on the role and would love to put his "spin" on it.

"I've told you this before. I think Josh Trank is a very talented film maker," he said. "I think that if it were all to come together and land in my pocket, I would absolutely love to put a new face and a new spin on a character, one that people have already done and do something different with it."

The Fantastic Four is scheduled to release on Jun. 19, 2015.
