Everyone had a good time recreating another decade for the 1960’s-based X-Men: First Class. They had so much fun that it’s sparked the conversation of where to go in the sequels.
Matthew Vaughn said:
“1962 is far more grounded in the world of the ’50s. I think it takes about five years for a decade to really start getting its identity, so the fun thing about this for me would be doing [a sequel] in the latter part of the decade, where you’ve got The Rolling Stones, The Beatles, Flower Power…”
Bryan Singer also discussed setting the sequels in the 1970’s and 1980’s respectively, which I’m on board with. Especially if the story takes a radical jump between films as well, and the details are filled in as the plot unfolds. Like, why does Magneto suddenly have a Kid n’ Play high-top fade??
