 Freddie Frances was inspired by Oakley Court's exteriors and long wished to set a film there; his 1970 "Mumsy, Nanny, Sonny, and Girly" was written specially to take advantage of the unique landscaping and architecture.It is perhaps best known as Dr. Frank N. Furter's castle (called The Frankenstein Place) in "The Rocky Horror Picture Show" (1975).During filming, actress Susan Sarandon who played Janet Weiss came down with pneumonia because both Oakley Court and Bray Studios had no heat or bathrooms and also because at the time Oakley Court was in horrible condition.
