20th Century Fox is rumored to be working on an “X-Force” film. Marvel Comics

Will an “X-Force” film be following the release of the “X-Men” movie “X-Men: Days of Future Past”? X-Men Films has reported that 20th Century Fox has registered the domain name for X-ForceMovie.com. According to the site, this is consistent with the pattern of how most “X-Men” film titles have been leaked to the public.

Mark Millar, a creative consultant for the studio, previously teased the idea that an “X-Force” film might be in the works, according to X-Men Films. “You have to remember that Fox grabbed the X-Men back in the ’90s because it was the biggest franchise in the world. So X-Force or Cable or Deadpool -- all these amazing characters are things we haven’t really gotten to yet,” Millar said. “‘X-Force’ #1 was the second-biggest book of all time behind Jim Lee’s ‘X-Men’ #1, so there’s an immediate brand recognition to that stuff and a build in fanbase,” he added.

The next "X-Men" film is being directed by Bryan Singer and will see the return of several familiar faces, including Halle Berry, Hugh Jackman, Jennifer Lawrence and Patrick Stewart.

“X-Men: Days of Future Past” is planned to hit U.S. theaters on July 18 of next year.
