Production History
In 2010, 20th Century Fox announced that it envisioned X-Men: First Class as the first leg of a second X-Men trilogy.

In 2011, X-Men: First Class director Matthew Vaughn speculated that a sequel could be set "in the latter part of the [1960s] where you’ve got The Stones, The Beatles, Flower Power." Actor James McAvoy expressed interest in seeing Charles Xavier get “really messed up” in the sequel and speculated that a third film could show his transition into a character closer to the one played by Patrick Stewart in the original trilogy.

Actress Jennifer Lawrence expressed interest in reprising her role as Mystique in a sequel. Actress Rose Byrne revealed that she had signed on for two more films in the X-Men franchise.
