Actor Ralph Fiennes has heaped praise on his THE DUCHESS co-star Keira Knightley for her mature approach to their tense scenes together.
The veteran actor was amazed at the 23-year-old Atonement star's talent - and insists she has the crucial 'it' factor that could make her one of Hollywood's hottest properties.
And he was impressed with the way she grappled with the part of Georgiana Cavendish opposite his role as her loveless husband in the period drama.
He tells USA Today newspaper, "Keira has great clarity as a person... amazingly open for her age. She has a great maturity and an openness and a natural spontaneity, a vivacity. Thats a crucial thing you cant act. She has it.
