But one thing that we do know is that it will be an event film that is scheduled for a summer 2020 release. And as many of us wait to find out what the film could be about, reports of who will star in it have emerged. Multiple reports say that BlacKkKlansman star John David Washington, High Life star Robert Pattinson, and Widows star Elizabeth Debicki are poised to have roles in Nolan’s mysterious new film.

An official trailer for BlacKkKlansman, which is directed by Spike Lee and produced by Jordan Peele, was released this week by Focus Features.
