LATEST: As US film critic Roger Ebert recovers from cancer surgery, five guest hosts will fill-in alongside RICHARD ROPER on the pair's movie review show. A Mighty Wind star Fred Willard, novelist John Ridley and FRIENDS star Aisha Tyler will appear on the shows beginning on 24 September (06). Chicago Tribune movie critic Michael Phillips and entertainment reporter TONI SENECAL round out the list. Ebert, 64, has spent two months in hospital while being treated for recurrent salivary cancer. Ebert's vocal cords have become so weak during the surgery that he is undergoing rehabilitation to help return his voice to normal.
