Behind the scenes
Prior to being cast for the role of Quirrell, Hart had never read any of the Harry Potter books. To prepare for the role, he went to a local bookshop and was given a copy of the second book in the series, Harry Potter and the Chamber of Secrets and became confused upon reading the book, not yet knowing that his character did not survive past the first instalment in the series.
