Christopher Nolan has started filming his latest Batman film in London.
Warner Bros. Pictures says principal photography began this week on The Dark Knight Rises, the conclusion to Nolan's Batman trilogy.
Film crew and blacked-out cars were spotted at night near Charter House Square in the capital, where fans in Batman t-shirts flocked in the hope of getting autographs.
A bystander said: "We've seen people in American cop uniforms going in and out so I reckon they're filming Gotham City night scenes in there."
The film will also be shot in India, Scotland and the American cities of New York, Los Angeles and Pittsburgh.
Christian Bale returns as Bruce Wayne and Batman. Michael Caine, Gary Oldman and Morgan Freeman are also returning to the cast. Newcomers for the third installment in the franchise include Anne Hathaway, Marion Cotillard, Tom Hardy and Joseph Gordon-Levitt.
Joseph, Tom and Marion also appeared in Nolan's 2010 film Inception.
The Dark Knight Rises is slated for release in July next year.
