Jack Birch, Thora Birch's father and manager, insisted on being present on the closed set of this movie to watch the filming of her sex scenes with Dean Winters.
Said one on-set source: "It was so wrong. The director is saying, 'Harder! Faster!' and the father is giving Winters the thumbs up." Because it is industry practice for sex scenes to be filmed on a closed set, the production crew was hesitant to allow Birch's father on the set. But "all of a sudden, the front door is being kicked in. Her father was threatening to kill the assistant directors. Then he threatens to pull her from the movie with three days of shooting left." Filming the scene took fourteen takes. "It was the most bizarre, perverse scene," said the witness.
