Fingersmith was made into a serial for BBC One in 2005, starring Sally Hawkins, Elaine Cassidy and Imelda Staunton. Waters approved of the adaptation, calling it "a really good quality show", and said it was "very faithful to the book. It was spookily faithful to the book at times, which was exciting." The novel was later adapted again by South Korean director Park Chan-wook into the 2016 film The Handmaiden, which set the story in South Korea in the 1930s.
In 2005, Waters received the highest bid (£1,000) during a charity auction in which the prize was the opportunity to have the winner's name immortalised in The Night Watch. The auction featured many notable British novelists, and the name of the bidder, author Martina Cole, appeared in Waters' novel.
