'About Time' rumoured to be Curtis' last film

About Time: Films return to Somerset House

London's original open-air cinema kicks off again tonight with the world premiere of a new film shot in the capital. Somerset House will be showing films for the next two weeks in its grand outdoor courtyard.

Tonight's premiere of "About Time", directed by Richard Curtis, follows a young man who discovers he can time travel. Parts of the film were shot just minutes away from where it will be screened this evening.
