LATEST: SIR Ben Kingsley blames racism he suffered growing up in England for his obsession with using his title.

The actor was criticised by other titled British actors after his knighthood was used on the poster for new movie Lucky Number Slevin.

Co-stars have also revealed Kingsley demanded he be called "Sir Ben" on the set of films.

The Oscar winner has apologised, insisting his title was put on the movie poster without his knowledge by a "well-meaning executive", and blaming his behaviour on his immense pride at overcoming a difficult childhood.

The actor - who is half Indian - says, "I've always been proud of the title. I think it's a reflection of how an uncomfortable childhood can lead to high achievement."
