According to some sources, the official release date for the sequel to X-Men: First Class is set to July 18th, 2014. Still untitled, the film ? again directed by Matthew Vaughn ? will go into production in early 2013.
While no official casting has been announced, it?s assumed that at the very least James McAvoy, Michael Fassbender and Jennifer Lawrence are returning ? with Lawrence the subject of a bit of a scheduling war earlier this year, as Fox and Lionsgate both worked to set their production dates for the X-Men sequel and The Hunger Games: Catching Fire, respectively. Ultimately, Fox agreed to wait a few months on X-Men, though this means the Hunger Games sequel — beginning production this fall — had to be especially fast-tracked, since Fox contractually has first option on the much sought-after Lawrence.
