A mysterious stranger arrives at a boarding house in London and inquires about the advertised room to let. The landlady has some reservations about him but his good manners, personal charisma and willingness to pay his rent in advance convinces her he will be a respectable lodger. How many times have we seen movies that open with the same scenario where the new boarder turns out to be a suspicious character and possibly mentally unhinged? Alfred Hitchcock’s The Lodger (1927), Man in the Attic (1953), Roman Polanski’s The Tenant (1976) and The Minus Man (1999) are some of the more famous examples of this. The 1935 British film, The Passing of the Third Floor Back, however, gives us a protagonist who could be some kind of savior in disguise, a spiritual being who has come to help the unhappy and misanthropic boarders. Is he an angel, a Christ figure or maybe a figment of someone’s imagination?
