A Casa dos Fantasmas

In 1963 Hammer films made their own version of JD Priestly's "The old dark House" and against all the normal practices of Hammer hired B Picture Horror legend William Castle to direct. Hammer Regular Terrance Fisher seems to have taken umbrage at this and the following year made this film independently. The budget is a fraction of the hammer version, music is added and famous crooner Pat Boone takes the lead the names are changed from Fem and Penderel but otherwise the story is the same (apart from one small and nonsensical twist at the end). Especially notable in this version are Valentine Dyall and British sit com regular Eric Chitty.
