Christopher Nolan is getting ready to make our brains earn their keep once again with his upcoming sci-fi action drama Tenet.

The director has remained tight-lipped as to what the story’s about, with the only really concrete info so far being that there’s an international espionage angle.

The film stars John David Washington, Robert Pattinson, Elizabeth Debicki, Michael Caine and Kenneth Branagh and appears to be a return to Memento and Inception territory for Nolan.

Here’s the new trailer – Tenet is one palindrome that we can’t wait to watch when cinemas reopen later this year.
