Oscar-winning actor Ben Kingsley left legendary director ROMAN POLANSKI speechless when he pretended not to know the film-maker on the set of the upcoming Oliver Twist remake.

The GANDHI star prepared for his role as pick pocket gang leader FAGAN by greeting crew and cast members in character every morning, and allowed his alter-ego to forget Polanski's identity.

The 61-year-old says, "I allowed Fagin to forget who everyone was. I'd say to Roman Polanski, 'Good morning, who are you?'"
