Alice Braga has replaced Rosario Dawson in X-Men: New Mutants movie. The Men in Black II actress had reportedly negotiated with Fox about portraying Dr. Ceilia Reyes, a mutant and medical doctor, in the forthcoming X-Men spin-off but she has now pulled out from the movie.

Screenwriter Josh Boone has penned the script with Kante Gwaltney, Simon Kinberg and Karen Rosenfelt on board with producing duties.

Not much is known about the project, but Boone recently shared that his take on the new mutant movie will see a team of younger mutants end up forming a new team and will be a full-fledged horror.

"We are making a full-fledged horror movie set within the X-Men universe. There are no costumes. There are no supervillains. We're trying to do something very, very different," Boone said.

Game of Thrones actress Maisie Williams will star as Rahne Sinclair, aka Wolfsbane, a girl struggling to reconcile her religious beliefs with her power to turn into a wolf. Anya Taylor-Joy will play llyana Rasputin, code-named Magik, who has learned sorcery and uses teleportation discs to travel.

James McAvoy, who starred as Professor Xavier in the First Class franchise, is also expected to appear in the film.

The set construction will begin in January in Montreal, where X-Men:Days of Future Past and X-Men: Apocalypse were shot.
