Apocalypse is going to be played by Oscar Isaac. He is a 36 year old actor that is well known for his lead roles in Inside Llewyn Davis, A most Violent Year and even in the upcoming Star Wars: The Force Awakens as Poe Dameron.
The younger versions of Storm, Summers and Jean Gray will be played by Sophie Turner, Tye Sharidan and Alexandra Shipp, respectively. It looks like Nightcrawler will be in the film, as well as Angel, with Oliva Munn playing Psylocke. Lucas Till will return as Havok, with Caliban making an appearance and William Stryker played by Josh Helman.
The casting announcements came more than a year ago and created just enough buzz to keep X-Men: Apocalypse in the front of the minds of fans around the world. The movie will be released globally and is expected to do just as well as the others have at the box office.
