Harrison Ford, Sir Ben Kingsley and Hailee Steinfeld shocked students at a London school by making a surprise visit to discuss life in Hollywood.

The actors are supporting the work of charity FilmClub, which aims to increase educational achievements among youngsters across the U.K.

As part of the campaign, the stars visited pupils at Westminster Academy earlier this week (begs07Oct13) to discuss their film careers and new movie Ender's Game, and they also participated in a question-and-answer session where they were grilled by students on their movie experiences.

Ford tells the Bbc, "I'm a working actor so if we could talk practically about the business of storytelling with young people, I think it is a useful and social purpose."

Gandhi star Kingsley adds, "It is always an opportunity for me to be honest and clear about what I do for a living."
