Two of Britain's finest actors are back on screen this week and Jim White gets to talk to both of them: Peter O'Toole , who plays Priam in the long-awaited release of Troy, the big-budget Hollywood version of Homer's epic; and, liberated from the long white hair and beard of Gandalf in the Lord of the Rings trilogy, Ian McKellen chalks up another fine performance as he confronts some very personal ghosts in a new film, Emile.
