Christopher Nolan has decided to continue his relationship with Warner Bros., and direct his next film for the studio - we just don't know what it'll be called yet. In fact, all we do know is that it'll be released on 21st of July, 2017, one week before Marvel and Sony's Spider-Man reboot, and the same day as Pitch Perfect 3 and Luc Besson‘s Valerian. Hard luck guys.
Nolan's films are always shrouded in secrecy but without so much as a title to go on, speculating on the plot of this one is pretty much impossible. Fans of the director's acclaimed Batman movies will be hoping it's something comic book related, but that would seem unlikely given Nolan's past comments about concentrating on original projects from here on out.
One thing is for sure: whatever it's called, whatever it's about, it's going to be big!
