Keira Knightley attended the premiere of her new film A Dangerous Method at the BFI London Film Festival in a two-tone calf grazing dress that would be on the wrong side of boring were it not for the criss-cross bodice that shows just the most modest bit of skin. KK certainly has the abdominals to pull this off, but what do you think about the star's dress? Xcellent or no thanx?
