Running Scared (1972) Directed by David Hemmings.

Update June 2024:

I Start Counting, and Three Into Two Won't Go are out now on Blu-Ray. Unman, Wittering and Zigo has for some inexplicable reason (probably to do with copyright) only a Region 1 Limited Edition Blu-Ray release, but is available to rent on Amazon Prime. Baxter  is now available and well worth watching. No sign of the others, other than a print of Running Scared was shown at Braunston Marina (where some of the film was shot) in 2011!
