“Another thing that’s been introduced in the comics is a big alien, interstellar tenant within the X-Men universe that hasn’t been explored. And to me, that might be kind of fun because I’m a huge Star Wars and Star Trek fan, and exploring the X-Men universe and being able to utilize that would be exciting, visually.”
This sounds like an obvious set up to do the "The Dark Phoenix Saga" proper justice. And if that's the case, then it would likely mean introducing other intergalactic elements into the mix, such as the Starjammers (which includes Cyclops' space pirate father, Corsair), the race of beings known as the Shiar, and hopefully the Imperial Guard with one of my favorite characters, Gladiator. Singer also confirmed the next film will be set in the '90s just as recent rumors claimed.
All I'll say is that hints to where the franchise is going are all over X-Men: Apocalypse, so be sure to check it out on May 27th. And when you're done come back and check out my review.
