Every time I see Coronation Street's Gail McIntyre on screen these days, I find myself feeling unnerved - she seems to be morphing into arch-villain Mrs Danvers (brilliantly played by Judith Anderson in Hitchcock's unbeatable film version of Daphne du Maurier's Rebecca). It's the shorter hair, the stern expression, the high necklines, the icy gleam in the eye. I'm loving it! What next for Gail?
