Different Locations.

There have been several different film productions of the play The Cat and the Canary (1922) and each has had a different location.

In the 1927 movie the mansion of Cyrus West where the heirs gathered for the reading of his will was described in a title as being by the Hudson River. It had a dramatic look with about five towers, maybe one in the middle and four at the corners, topped by very tall conical roofs taller than the towers beneath them. Unfortunately the presumable matte painting of the mansion was not seen very well in the film.

The Cat Creeps (1930) is considered a lost film, and I have no idea where the mansion was supposed to be or what it looked like.

In The Cat and the Canary (1939) the mansion of Cyrus Norman was on an island in a Louisiana Bayou. It looked like a fairly typical southern plantation mansion.

In The Cat and the Canary (1979) the setting is Glencliffe Manor, an English country House, in 1924. The exteriors and interiors of the mansion were portrayed by Pyrford Court in Surrey, England. It is a redbrick neo Georgian mansion with mostly white interiors.

Pyrford Court has appeared in other movies and tv shows, most famously in The Omen (1976). Other films with Pyrford Court include Sky Pirates (1980), Tales From the Crypt (1972), and The Mind of Mr. Soames (1970).
