Fox owns the rights to the X-Men and Fantastic Four franchises, so the mystery 2018 Marvel film could draw from either of those. It's not unthinkable that the project might even be a crossover between the two.

James Mangold is returning to direct the sequel to The Wolverine, which earned more than $414 million globally last year. The Fantastic Four reboot recently solidified its cast, with Michael B. Jordan, Kate Mara, Jamie Bell and Miles Teller taking on the roles of the superhero team. It's slated for a June 19, 2015, release.

Fox also announced a release date for Liam Neeson starrer Taken 3, slating it for Jan. 9, 2015. An unnamed Ridley Scott film is set for March 4, 2016.

Fox shifted the release dates for several projects. Matthew Vaughn's The Secret Service has been moved up from March 6, 2015, to October 24, 2014; an untitled Vince Vaughn film moved back from October 24 to March 6, 2015; and Frankenstein, starring Daniel Radcliffe, is moving from January 16, 2015, to October 2, 2015.
