And congratulations to our winner …… for correct answer that David Niven was the only one who won an Oscar in Best Actor Academy Award for the movie Separate Tables. None of the others won Oscars for Best Actor. Richard Burton once held the record with Peter O'Toole, he currently holds the record for the most Oscar acting nominations (7) without a single win. In 2007, that record was broken, when O'Toole was nominated and lost yet again, for the film "Venus". Cary Grant was nominated twice for Penny Serenade and None But the Lonely Heart but never won an oscar.
