If you happen to be or go to Amsterdam, you shouldn't miss the Amsterdam Historic Museum. The place to learn about Amsterdam through out the ages.
The museum's permanent collection includes a movie made by Dutch Jews in hiding during World War II.
Boredom was Motive for Movie Making
In 1983, Hololcaust survivor Harry Swaab, said his idea for the movie came up as a means against boredom. The group of people, in hiding above night club Alcazar downtown Amsterdam, "play acted" the rituals of their own daily reality: eating, dividing toilet paper, exercises in hiding within their hiding place.
Duikjoodbasis - Submarine
The Dutch word for submarine is duikboot. The expression for "going into hiding" is "onderduiken" (going under, as in diving).
The film makers changed boot (boat) into jood (Jew) [eode]which rhymes with boat.
Alcazar was their base (basis). Wordplay, lost in translation.
On May 28, 1943, the film makers were taken from their place of hiding, and transported to a concentration camp. No telling how many of them survived. Harry Swaab did, and so did his movie.
