20th Century Fox has set dates for various upcoming films, including two mystery Marvel movies, and a possible "Avatar" sequel.

According to Variety, an untitled Marvel movie will be coming to theaters on November 2, 2018, with another slotted for February 14 of 2019. The first film, should it stick to its release date, would be going against Disney’s live-action adaptation of “Mulan” -- so it stands to reason it should be a fairly big Marvel franchise that’s getting the date.

As far as what Marvel movies the studio could be prepping for, there are many to choose from. They currently hold the rights to the “Deadpool” franchise -- which already has a sequel in the works -- the “X-Men” franchise, as well as the “Fantastic Four” series -- though it’s not likely they’ll be revisiting that property anytime soon. The “Gambit” movie could be the second mystery film, although it has still not started pre-production.

Fox additionally announced that the sequel to 2012’s “Prometheus," “Alien: Covenant," will have its release date pushed up from August 4 to May 19, 2017, which would coincide with the poster they released yesterday. “Kingsman: The Golden Circle” also saw its release date moved -- this time going backwards; instead of June 16, 2017, the film will now release on October 6.

Lastly, Fox set December 21, 2018 as the date for a film by James Cameron’s Lightstorm Entertainment. The film is widely rumored to be the highly-anticipated sequel to the 2009 success known as “Avatar." No official word on whether or not the oft-delayed sequel is the one coming in 2018, but the original “Avatar” also released in December, during the same week.
