To be fair, it's over 30 years ago since I saw this film in the days when there were only 3 channels. So it was either this, a documentary about basket weaving on BBC1, or 'The Money Programme' on BBC2.
It must have had an impact on me though to have remembered it and looked it up on IMDB all these years later.
I basically remember about 20 minutes of actual action in the cablecar, and the rest of the 3 hours or whatever it was, as the characters dull backstories delivered by rather annoying and tedious flashbacks, just to leave you tutting when you thought it was just starting to get slightly interesting.
You could probably make quite a good comedy spoof movie these days based on 'Hanging by a thread' and be sure nobody would take you to court for copyright theft, as the few people who watched it probably won't remember it, and the people who produced probably won't want to own up to it.
If you've stolen money from a children's cancer charity collection box or drowned some kittens and want to punish yourself for it, then watch this film. Your debt to society will be paid in full.
Who am I kidding though. About as many people are going to read this review as have met a Jehovas witness that takes 'no' for an answer.
