Rosario Dawson may soon be pulling double duty in the Marvel Universe -- the actress is in talks to join the cast of Twentieth Century Fox’s New Mutants reports The Hollywood Reporter.

If negotiations are successful, Dawson, who already plays no-nonsense nurse Claire in Marvel’s various Netflix series, will play Dr. Cecilia Reyes, who has the ability to generate a protective field around herself.  She will serve as a mentor to the young mutants on which the movie centers.

Masie Williams (Game of Thrones) and Anya Taylor-Joy (The Witch, Split) have already signed on as Wolfsbane and Magik respectively (see “Maisie Williams, Anya Taylor-Joy Cast in 'New Mutants'”).  The movie is being directed by Josh Boone (The Fault in Our Stars), based on a script by Boone and Knate Lee.

In a separate report from Entertainment Weekly, Boone revealed that New Mutants is embracing a different genre: horror.  “There are no costumes,” he told EW.  “There are no supervillains.  We’re trying to do something very, very different.”

The movie is inspired by “The Demon Bear Saga” storyline that kicked off in issue #18 (1984), the point at which Bill Sienkiewicz took over art duties with Chris Claremont at the writing helm.  In the arc, the teenage heroes-in-training find themselves isolated by a freak snowstorm from their mentors, and they must overcome their personal fears and interpersonal differences to save one of their own.  Boone described the comic series from that era as “a darker and more surreal and impressionistic X-Men series than we’d ever seen before.  It felt like Stephen King meets John Hughes.”

According to a source, the movie will change the setting, putting the teens in an isolated facility where they are being held against their will, and Boone is aiming for a PG-13 rating for New Mutants.  It will release on April 13, 2018 (see “Best in Shows--Q2 2018”).
