As it's a short, also starring Nicol Williamson, this would make an ideal DVD extra. How about a BFI Flipside release of Inadmissable Evidence?

"YOUTH is important to the film business", everybody says pompously. So why won't somebody at least give a showing to Christopher Miles? In six days, and for less than �6,000, he has written, produced and directed "The Six-Sided Triangle" (U).
GAMBLE
Chris has mortgaged his flat and is broke. He raised money from friends and the Boulting Brothers for this gamble. The film shows the eternal triangle as it might have been filmed by a silent film-maker and by British, French, Italian, Japanese and Norwegian producers.
The star is Christopher's sister, Sarah Miles, superbly versatile as all six heroines. This wry, sly, witty half-hour film shows a talent worth encouraging. But distributors are sitting very tight and young Miles is wondering if the film will EVER be shown. I hope somebody will give this bright young man a break.

I think I recorded Channel 4's broadcast of The Six-Sided Triangle late one Saturday night, circa 1985. Not sure if I still have it. An amusing little film, as I recall. They used to show a lot of those old shorts at various times of the day (e.g. And So to Work and John Schlesinger's Terminus),. Another one I liked was Rupture by Pierre �taix, who was also the star. Thankfully, this is available on DVD.
