Sean Biggerstaff (born 15 March 1983)[1] is a Scottish actor and musician, who portrayed Oliver Wood in the Harry Potter film series.
Biggerstaff obtained his first professional acting role at ten, playing the son of MacDuff in a Michael Boyd production of Macbeth at the Tron Theatre, Glasgow. He then joined the Scottish Youth Theatre and spent six years with the group. In 1996, at the age of 13, Biggerstaff secured his first major TV role, playing Young Darren in the BBC production of The Crow Road. At 14 he was cast by future fellow Harry Potter actor Alan Rickman in his new movie, The Winter Guest, as Tom, a mischievous schoolboy. In a 2002 interview, Biggerstaff recalled: "It was while at the Scottish Youth Theatre that I was chosen for The Winter Guest. Alan Rickman (known to most of the kids as "the bad guy from Die Hard") popped along one day looking for two boys to accompany him to the coldest place on Earth, Fife, for two months to make a film. Myself and the suspicious character that is Douglas Murphy were the lucky ones."
