Sheridan's harrowing new look: Actress's transformation for role as cancer patient is revealed ahead of upcoming BBC drama

 Exhausted, washed out and hairless, even down to her missing eyebrows, Sheridan Smith’s physical transformation is painful to see.

The award-winning actress, best known for her recent portrayal of flame-haired singer Cilla Black, has opened up about the emotional impact of playing cancer patient Lisa Lynch in an upcoming drama.
Speaking tearfully after a screening of The C Word, which comes to BBC1 later this year, Miss Smith, 33, said the role ‘changed my life’ and revealed the effect of Mrs Lynch’s death during the production.
