Found it. 1937. It's not available for streaming but I'll keep an eye out for it.
Thanks!
I bought if off ebay for a pretty cheap price. It was the wrong region code but I had read that my DVD player could be hacked to play any region and that turned out to be true.
I also noticed my computer will play it with no problem. It includes a whole lot of extra information both from Michael Powell and his widow. They also had a short movie of a return to Foula which is the island they filmed on. Nearly all the actors came back tho they were mostly in their 90s. Many of the Island’s inhabitants who were extras in the original movie were still alive too. The main actress who was a real beauty did not come but she was still alive as she lived to 93.
The actors director film crew etc. had to build their own shelter. Foula was just as remote as St. Kilda but was close to main shipping lanes so was far less isolated.
The owner of St. Kilda would not let them film there so they found what was basicall a twin to St. Kilda in the Orkneys I think. That Island such a close match it was almost weird. St. Kilda has the highest cliffs in Scotland and Foula had the exact same type of sheer cliffs which were only something like 10 feet less that Sr. Kilda.
