Prior to Curtis's taking the role of director, the producers of the film offered Bob Fosse, who was directing his recent film at the time, Sweet Charity to direct the film next. Fosse was intrigued with the project and saw it as a challenge to direct a non-musical and a dark horror story, which wasn't his milieu. Fosse was especially interested in the story's central question; How much of a beating can a happy family withstand? Fosse and the producers settled on a summer 1970 shoot date, and Fosse took a trip to California to look for his haunted mansion. Eventually, Fosse's involvement with the project never materialized and he went on to direct Cabaret, instead.
