Following the success of "Deadpool", 20th Century Fox was eager to get a sequel moving forward. However, the highly-anticipated "Deadpool 2" is facing a major roadblock after director Tim Miller dropped out of the project due to creative differences with both the studio and Ryan Reynolds last month.

While the second movie has yet to find a new director, the studio is reportedly already developing a third "Deadpool" movie. Insiders tell The Hollywood Reporter that Fox is in search of a director to helm "Deadpool 3", with the black-ops X-Force team led by Cable being included and possibly playing a prominent role.

The alleged sources also say that Fox is planning another reboot of "X-Men" movie franchise. Bryan Singer, who helmed four "X-Men" movies, probably won't be back, but Simon Kinberg is already working on a new script.

The main actors, including Jennifer Lawrence, Michael Fassbender, James McAvoy and Nicholas Hoult, likely won't return as they have come to the end of their three-picture contracts after starring in "X-Men: Apocalypse". However, sources say that the studio "optimistically" wants them to be back even though it will be costly.

Additionally, the studio has a big project that's still on hold. Another "X-Men" spin-off "Gambit", which has Channing Tatum attached to star, failed to begin production as planned. It lost its director, Doug Liman, back in August.

Many of its big projects are facing roadblocks, but the studio apparently still has hope as "The New Mutants" remains on track. Sources say that director Josh Boone eyes a spring 2017 start date for the "X-Men" spin-off featuring a group of young mutants who study and train at the Xavier School for Gifted Youngsters.
