Production According to director Reginald LeBorg, the film was financed on $300,000. He suggested to the producers that it could be made in as little as "ten or eleven days." The small budget would preclude any set construction or elaborate props, requiring that they shoot in "an office, or go on the road, or go to the beach."Dixon, 1992 p. 113
LeBorg's movie provided little in the way of action, and the producers inserted a number of automobile chases. LeBorg declined to provide the editing and a cutter, Herbert L. Strock (director of Gog (1954) and Battle Taxi (1955)), was engaged to act as editorial supervisor.Dixon, 1992 p. 113, p. 159
So Evil, My Sister was LeBorg's last feature film of his career.Dixon, 1992 p. 37
Release So Evil, My Sister never was given a general theatrical release by Zenith International and Joseph Brenner Associates. The production has since appeared on Home Video.Dixon, 1992 p. 38
