Christopher Nolan’s Next Film Lands 2017 Release Date From Warner Bros.

It’s a mystery, folks!

Christopher Nolan is set to direct an untitled movie for Warner Bros. that will be released on July 21, 2017, the studio announced Tuesday.

In keeping with Nolan’s penchant for secrecy, details of the project are being kept under wraps.

The Untitled Christopher Nolan Project is now set for release the same day as “Pitch Perfect 3” and Luc Besson‘s “Valerian” as well as an untitled animated movie from 20th Century Fox. It arrives one week after the next “Planet of the Apes” movie and one week before Sony’s untitled “Spider-Man” movie.

Nolan directed the “Dark Knight” trilogy for Warner Bros. and made sure the studio had a piece of his most recent hit, the original sci-fi movie “Interstellar,” so it’s a natural fit for the celebrated filmmaker.

Nolan, who also directed “Memento” and “Inception” and earned Oscar nominations for writing both of them, is represented by WME.
