When the inmates were totally exhausted, after having worked for 12 hours a day, or if they were too ill or too weak to work, they were then transferred to the Revier ("Krankenrevier", sick barrack) or other places for extermination.
A revier (abbreviated from German Krankenrevier, or "sick bay", "dispensary") in the language of Nazi camps was a barrack for sick concentration camp inmates.
Two exceptions are the Tarzan films that Revier co-directed for Edgar Rice Burroughs; one of these, The Son of Tarzan (1920), was a considerable hit.
