Ben Kingsley compliments Jake Gyllenhaal for his excellent North London accent in 'Prince of Persia,' noting how the accent perfectly suits his character of Prince Dastan on 'Good Morning America' (weekdays, 7AM ET on ABC).

"Christina Blange! Ready for your close-up?!" So that he wouldn't have to hear that for the rest of his life, Ben Kingsley (that would be SIR Ben Kingsley to us) changed his name from Krishna Bhanji. He explained the whole story on 'Late Show With David Letterman' (weeknights, 11:35PM ET on CBS).

As movie trivia experts, however, we also happen to know that Kingsley derived his stage name from his grandfather's nickname, 'Clove King.' His grandfather was a spice trader in Zanzibar. You're welcome for the party trivia. Happy to help.
