Trivia: Cobra's car was actually owned by Stallone and the studio built doubles for the stunts.
Trivia: Brian Thompson, who played the Night Slasher, admitted in a recent interview that during filming, he had no idea what his character was about or why he and his gang were randomly killing people. When he asked Stallone who wrote the script, he couldn't even give him an answer. (Director George Pan Cosmatos made no effort to help.) Brian was eventually forced to come up with his own explanation to assist his performance. He wrote a two-page essay and just worked from that.
