Trivia / Prison

• The Danza: Tom "Tiny" Liston plays a guy called Tiny.
• Follow the Leader: Few other films, where executed inmates would come back as electrically charged ghosts, came after this film, including The Chair, The Horror Show and Shocker
• Vindicated by Cable: Wasn't given a wide release but quickly developed a cult following. Director Renny Harlin impressed enough people making a low-budget horror movie with memorable death scenes that he was tagged to direct A Nightmare on Elm Street 4: The Dream Master.
