This is the movie description
The incredible story of Avraham Sutskever, the greatest Yiddish poet, who saved manuscripts from the Nazis, survived WWII due to Stalin's special rescue plane, testified in the Nuremberg Trials, and died anonymously in Tel Aviv.
As long as Abraham Sutskever lived, he wouldn't let a film about his life be made. Today, eight years after his passing, Black Honey tells the incredible story of the greatest Yiddish poet of modern times. The man who led the Paper Brigade underground movement that saved Jewish manuscripts from the Nazis, survived the WWII due to Stalin sending him a private rescue plane, testified in the Nuremberg Trials, and immigrated to Israel in 1947 where he led Yiddish culture while writing in astonishing vitality.
Once the people filmed in new footage are credited, that will relegate Hitler to a much lower position in the cast. Hence, the "Stars" of the film as listed on IMDb should change. In addition, any other people shown in archive footage may be submitted to the Cast with "archive footage" attributes.
As to whether Hitler should be listed at all, please check the documentary and see whether, indeed, there is any archive footage showing Hitler in the film at all. If so, the "archive footage" credit should be kept, but if not, you should submit a deletion for that credit.
I hope this helps.
Naomi: Hitler also has an IMDb name page and he actually has over 1000 ”archive footage” credits. Basically if there’s an documentary about the WW2, Hitler will appear in some filmed form or another. Photos on wall doesn’t count, though.
