The Witnesses (1961)

This film brings to life a vanished world: that of the Warsaw Ghetto, destroyed by the Nazis after the 1944 uprising. Two authentic "reconstruction" sources have been used to this end: photographic and cinematographic documents recorded at the time and discovered in Poland, East Germany, Israel and France; and the oral testimonies of 44 survivors, invited to evoke their personal tragedy in front of the images put before their eyes.

Unfortunately the movie The Witnesses is not yet available on HBO Max.
