“I had a whole different idea of how X-Men should go,” Kingsman: The Secret Service director Matthew Vaughn tells MTV News. “I thought Days of Future Past should be the next one and be set in the ’80s. So, when I wrote the treatment, I then wrote Kingsman and got confused about which film I should direct next. Then I said to Fox, ‘Let me do Kingsman now, get somebody else in and we’ll do the ’70s version, recast Wolverine, and then we do Days of Future Past with the new Wolverine and Hugh, and make it the biggest spectacle we’ve ever seen.”
