Having issues putting this up in "Suggest a Movie", so I'll do it here.
I saw part of *Dark Intruder* on late night local (analog-- who knew?) back in the Eighties. It was released theatrically but was in fact a failed pilot for a TV series. An off-beat western starring *Leslie* *Neilsen*, my first impression was that this had to be a lost pilot for *The Wild Wild West* TV series that went through revision, trading Neilsen out for Robert Conrad. (Kind of like Jeffrey Hunter's Captain Pike was replaced by Shatner's Captain Kirk on Star Trek.) The proposed opening gambit for a series to be called *Black Cloak* (I'm guessing it beat TWWW to the punch), it is a western heavy on gothic horror, set in fog-enshrouded San Francisco, and I thought it was extremely atmospheric and well done. Apparently Universal thought likewise, taking a production that came a cropper selling a series and releasing it on the big screen.
This film would be perfect for TCM's Underground. Are you listening, Bob and Ben?
