Fans of The Dark Knight director Christopher Nolan can treat themselves to a behind-the-scenes featurette courtesy of studio Warner Brothers.
The film, starring Leonardo DiCaprio as an espionage expert specialising in extracting ideas from the mind, has been shrouded in mystery from day one.
Unusually, there are no spoilers on the internet for fans, but the viral marketing campaign has included undecipherable manuals and images.
The featurette includes Nolan’s explanation of his use of practical, rather than CG, effects in the film, which has a huge international cast including Michael Caine, Ellen Page, Cillian Murphy and Tom Hardy.

Inception is released in the UK on July 16.
