The Ghost of St. Michael's is a 1941 British comedy-thriller film, produced by Ealing Studios. Will Hay, the film's star, replaced his sidekicks, Graham Moffatt and Moore Marriott, from his previous film Where's That Fire? with comedian Claude Hulbert. Hay and Hulbert would act together again in My Learned Friend two years later. Typical of comedies made during the war, it has an anti-Nazi plot.
