Warner Bros have revealed the title of Christopher Nolan's formerly top-secret upcoming movie, Tenet, along with new cast details.

Michael Caine will team up with the director once again, having previously worked together on box-office hits including Nolan's Batman trilogy and Inception.

Caine heads up a list of additions with a strong British flavour – renowned thespian Kenneth Branagh, and Kick-Ass and The Avengers' Aaron Taylor-Johnson.

Nolan's not keeping it all close to home for Tenet, however. The film looks to the world of international espionage and is set to shoot in at least seven countries, including India.

Accordingly, Bollywood veteran Dimple Kapadia joins the cast. Kapadia has previously appeared in at least one English-language film,  Somnath Sen's 2002 festival favourite Leela, and was last seen in Anees Bazmee's 2015 film Welcome Back.

Clemence Poesy, the French actress best known to English-speaking audiences for playing Fleur Delacour in the Harry Potter movies, adds additional international flavour.

The new members join BlacKkKlansman and Malcom X star John David Washington, Guardians of the Galaxy and The Great Gatsby's Elizabeth Debicki, and Twilight and possible soon-to-be The Batman star Robert Pattinson, whose appearances had already been confirmed, on an increasingly impressive cast list.

The movie may now be slightly less mysterious than it was 24 hours ago, but we still know very little. Even its title, Tenet, which has been newly revealed by Warners, doesn't give too much away.

We know that Nolan wrote the script and will direct, that the UK, India and Estonia are among the shooting locations, and that Pattinson was locked in a room where he was only allowed to read the script once when signing on to the movie.

We also know that Ludwig Goransson will handle the film's score, rather than frequent Nolan collaborator Hans Zimmer, and that Nolan's go-to editor Lee Smith was unavailable, leading to Jennifer Lame (of Manchester by the Sea fame) stepping in. Nolan will once again shoot the film using Imax equipment, with some scenes also shot on 70mm film, so expect a spectacle.

As regards plot and characters, however, the whole affair is being treated like a national secret, which is probably appropriate given the film’s subject matter.
