When the anthill torture scene was shot, producer Alex Gordon dropped ants on the bound heroine, Marla English. The ants, however, would promptly run away from her. After numerous failed attempts, English asked, "Look, you've got six ants there, isn't that enough?".
The film had been pre-sold on the basis of Al Kallis' poster of leading lady Marla English tied to an anthill. There was no such scene in the initial script--the scene wasn't written until much later.
