The film, which will be a sequel to "X-Men: First Class", will still mainly focus on the characters in their younger years, and while Jackman had a cameo in the original film, his role is said to be more substantial this time around.
Joining Jackman will be "First Class" stars James McAvoy, Michael Fassbender and Jennifer Lawrence.
