Sheridan Smith is hot property at the moment. She's set to star in The C Word, the one-off Lisa Lynch biopic, and Cilla, a drama charting Cilla Black's early years. She played the Bafta-winning lead role in ITV's Mrs Biggs and she's in The Widower tonight as the ill-fated wife of murderer Malcolm Webster.
But she wasn't always known for leading roles in big dramas.

Smith appears in the first episode of Jeff Pope's three-part thriller, starring Reece Shearsmith as murderer Malcom Webster. she will play Webster's first wife Claire, who he drugged and then killed in a car accident.

Love Soup 2005 - 2008

Two Pints of Lager and a Packet of Crisps 2001 - 2009
Playing cigarette and rich tea-loving Janet in long-running romcom Two Pints of Lager and a Packet of Crisps was something of a career defining role for Smith - and certainly the role she was best known for until recently.
Holby City 2001
