The Passing of Mr. Quin is a 1928 British mystery film which was co-directed by Leslie S. Hiscott and Julius Hagen, starring Clifford Heatherley, Mary Brough and Ursula Jeans. The film was based on the short story The Coming of Mr. Quin, part of the collection The Mysterious Mr. Quin, which was written by Agatha Christie. It was the first British film to be made of one of Christie's works. The short story was adapted by Hiscott, who would in 1931 direct Alibi, the first film to feature Christie's more well known Belgian detective Hercule Poirot. The film was made at Twickenham Studios in London.
