The original movies The Night Stalker and The Night Strangler have been shown on Creature Feature (CF), a late night horror host show out of California that’s available on Roku and YouTube. I think that both movies (The Night Stalker, Episode 06-259 of CF and The Night Strangler, Episode 06-266 of CF) run complete on the show, although you’ll need to fast forward through the horror host segments if you’re just interested in the movie. Each movie is also available for purchase on Amazon.
Thanks.
