X-Men: Days of Future Past screenwriter Simon Kinberg has reportedly finished his rewrite of The Fantastic Four, enabling Fox to begin testing actors for director Josh Trank's franchise reboot by the end of the month.

According to Variety, Saoirse Ronan (Atonement, Hanna) and Kate Mara (American Horror Story, House of Cards) are still expected to test for the role of Sue Storm, while Game of Thrones stars Kit Harington and Richard Madden are among those eyed to play Reed Richards. Miles Teller (Spectacular Now, Project X), long rumored as Mister Fantastic, seemed to indicate as recently as Tuesday that he's attached to the project, but sources tell the website he's merely testing for the part.

There's no mention of who might be under consideration for the role of The Thing.

That leaves perhaps the most most persistent casting rumor: that Michael B. Jordan, whose breakout role came in Trank's Chronicle, is set to play Johnny Storm, the Human Torch. Variety writes as if it's a done deal, saying he'll "test with the actors to see which group has the best chemistry." And judging from Jordan's comments on Tuesday's Late Show With David Letterman, where he was promoting the comedy That Awkward Moment, that could very well be the case.

“I mean, there’s a chance that I might be part of that film," he told Letterman. "I’m a big comic book guy, and the director Josh Trank is a big buddy of mine. We did Chronicle together, which is another film that did well for me. If it happens … maybe. [...] “It would be pretty cool to be the Human Torch. Yeah, it would be pretty cool. Yeah, it would.”
