Rosario Dawson pulls out of "X-Men"

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, which will see a team of younger mutants end up forming a new team, 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" actor 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, alongside Anya Taylor-Joy, who will play llyana Rasputin, a code-named Magik, who has learned sorcery and uses teleportation discs to travel.

James McAvoy, who currently stars 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.
