Following the filming of the rape scene, Gérard Zalcberg was so disgusted by what his character was scripted to act out that he started weeping and apologizing terribly to Caroline Munro. Munro comforted him, telling him she understood fully and reminding him that it was truly only acting, not real. The scene originally called for Munro to be partially nude, but she refused, claiming that was unnecessary and insisting that just showing some scenes which hinted at what was happening would get the basic idea across.
In the 2013 independent/student film "2013: Holocaust", Mitchum makes a cameo appearance as his Sam Morgan character from this movie. The main character of that movie, Hawk, mentions: "In 1987, I rescued him from this twisted hospital in Paris", putting an additional end to this movie.
