This film had a kind of haunting effect on me for over 25 years.
There is a scene in it where a man (later to be realised a doctor) drives his car away from a building in a manic fashion, trying to get away from something, and crashes, he stops dead, literally dead as his car hits an invisible barrier. Then other people come out of the building and comment on how it's their turn next etc. You know that moment in time has come back to me on a number of occasions through life and until last year I didn't have the faintest idea what film it came from. Then one night I stayed up until the early hours - the vegetable slot - and started watching this Very Low Budget but Very Intriguing film. Good lord, it must have been put together for a few shillings in the old money but HEY was it watchable. And then this same scene came up and it was like a sheer relief that a question that went unanswered for so long was finally solved.
If you get the chance, see this film. Don't expect Hollywood budgets or special effects 'cos they're not present - what you will see is the kind of solid acting and credible performances that only come from a cast who take pride in what they are doing; committing something to celluloid for the benefit of others and something sadly lacking nowadays - real movie art.
Not a masterpiece but certainly very worthy.
