Siân Thomas (born 20 September 1953) is a British[1] actress from Stratford-upon-Avon, England, who trained at the Central School of Speech and Drama.
[3] Based on a true story, the drama tells of the author Deric Longden's (played by Jim Broadbent) final years of marriage to his first wife Diana (Julie Walters) in the early 1980s and her fight against an illness which doctors then did not understand, later believed to be a form of chronic fatigue syndrome or myalgic encephalomyelitis.
Sian Thomas, who can get a laugh simply through the flick of an eyelid, is superb as a Courtauld-trained consultant longing to get her revenge on the corporate world.

[10] She has also been employed on several audiobooks including Allison Pearson's I Think I Love You and Marina Lewycka's A Short History of Tractors in Ukrainian.
