Margie Newton was acting in The Final Executioner (1984) and The Adventures of Hercules (1985) simultaneously. She hardly slept since she was working on "The Final Executioner" in the day and "The Adventures of Hercules" in the night. She lost 10 pounds and became anorexic due to the strenuous shooting schedules. That said, she enjoyed working on both films and found them to be great experience for her.
Woody Strode is dubbed by another actor in the English language version.
