Thomas has appeared on stage, on TV and in films such as Harry Potter and the Order of the Phoenix in which she played Amelia Bones.[2]

In 2002 she appeared in London's West End theatre production Up for Grabs with Madonna. The critic Michael Billington commented that "Madonna is not positively bad: just technically awkward. But, fortunately, she is buttressed by strong supporting players. 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."[3]

In 2004, Thomas played the leading role of Lady Macbeth in the Royal Shakespeare Company's production of Macbeth at Stratford-on-Avon. Billington wrote that "Sian Thomas was also born to play Lady Macbeth. She has the right mixture of attack, sexiness and emotional drive", adding that she gave Shakespeare's sometimes complex lines exactly the right stress to bring out the subtle antitheses. He noted, too, that she brought out the character's steadily growing "tactical and emotional isolation".[4]

In the musical Spring Awakening in London in 2009, she and Richard Cordery played "all the adult roles with cartoon-like aplomb".[5]

In 2010, Thomas played the leading role of the queen in the National Theatre Wales's production of Aeschylus's The Persians, described by The Guardian as "a tremendous performance as the queen, a woman of fiery splendour reduced to ululating agony as the disasters mount and she cries 'this is the peak of my misery'."[6]

In 2011, she played the leading lady Martha in the Northern Stage and Sheffield theatres co-production of Edward Albee's play Who's Afraid of Virginia Woolf?. The critic Clare Brennan commented that she and the leading man Jasper Britton "seize the parts for their own", as Thomas's Martha "part praying mantis, part puppet, jerks around the stage as if impelled by forces trying to rip free from her control – despair, grief and rage."[7]

From 2012 she appeared as Atorloppe in the BBC's Merlin series.[8]

Thomas has read poetry for the BBC Radio 3 programme Words and Music.[9] 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.[10]


Thomas spent part of her childhood living in Canada. She is the sister of the actress Sara Mair-Thomas.[11] Her partner is the British poet Tony Harrison.[12]
