Sheridan Smith is a real 'actor'. So many actors appear be re-vamping previous roles... Martin Shaw for example... good tho' he is always seems to be doing variations on Judge John Deed/ George Gently. Ms Smith can turn her hand to any role. She could be termed as ubiquitous , but in a good way for an actor. How on earth could anyone be so brilliant as the ditsy sister of 'Smiffy' in Gavin and Stacey, and a short time later play Mrs Biggs, the long-suffering wife of the ghastly Ronnie Biggs. The 'rap' sequence with James Cordon in one of the G&S episodes was nothing short of perfection.
I'm sorry to say such is the way of the media these days KatyK.... they take great delight in knocking someone down especially when they have built them up... James Cordon himself, for example. And the greatest example of the last twenty years..... Princess Diana.
