10 Movies That Were Shot In Secret

10. Predator 6

Though it's absolutely no secret that Prey director Dan Trachtenberg is currently in post-production on a new Predator film, Predator: Badlands, mere weeks ago 20th Century Studios executive Steve Asbell additionally confirmed that Trachtenberg had also shot another Predator film in total secrecy.

More to the point, this secret Predator film will actually release next year before Badlands. 

While we know that Badlands will star Elle Fanning as one of two sisters who comes face-to-face with the Predator, we know absolutely nothing about its mysterious predecessor, beyond the fact that Trachtenberg will serve as both writer and director.

Given that it's incredibly difficult for movies from major franchises to be filmed cloak-and-dagger style, it's truly shocking that nothing leaked out about this sequel's existence prior to it being casually announced in an interview with The Hollywood Reporter.

Considering Badlands is due to release on November 7 of next year, though, we're presumably going to find out everything about its secret forebear soon enough.
