First, the article about the TV series is in Hebrew, but you may read the auto-translation if you like.
Here's the trailer for "The Promise", where Jews are reported to be portrayed as blood-thirsty monsters:
Second, Colin Firth apparently agreed to participate in a movie that blatantly distorts history to portray Jews and Zionists as terrorists, an extreme anti-Zionist agitprop. Though the article say the script might have changed since it was reviewed, it is clear that all participants chose to take part while the script was written as it was:
Script Review Says Best Actor Nominee Colin Firth’s Next Project is Anti-Zionist
Directed by Michael Winterbottom, (Wonderland, The Road to Guantánamo), and partly backed by British taxpayers via the UK Film Council, The Promised Land presents a revisionist history of Palestine during World War II–one in which the British favor the Jews over the Arabs, the Jews repay British kindness with cruelty, and Arab violence against civilians and support for the Third Reich are airbrushed out of the picture.
The story centers around the real-life romance between two unlikely lovers, Shoshana Borochov and Thomas Wilkin. Borochov was the daughter of Dov Ber Borochov, a left-wing Zionist who saw the creation of Israel as part of the proletarian struggle. Wilkin was a British police officer responsible for tracking down members of the Jewish underground, particularly the infamous “Stern Gang.”
Before he was murdered during his arrest in 1942, Avraham “Yair” Stern had led a sensational and violent campaign to oppose British rule. His organization, “Fighters for the Freedom of Israel” (Lehi, in the Hebrew acronym) broke away from other Zionist groups and targeted British officials and police. He was regarded as an outlaw by many Jewish leaders, including the leaders of other Zionist underground organizations in Palestine.
At the time, the Holocaust was accelerating in Europe, while the British refused to allow the tide of Jewish refugees into Palestine. Though Palestine’s Arab leaders had revolted against British rule in the late 1930s, and soon took an active role in Hitler’s war effort, the British–after crushing the Arab rebellion–attempted (in vain) to appease Arab opinion with the White Paper of 1939, which severely restricted Jewish immigration.
The Promised Land ignores much of that context. Instead, it portrays the Jewish underground as a fascist, even pro-Nazi movement. The screenplay–a draft of which I have read–calls for graphic scenes of Arab suffering at the hands of Jewish terrorists and British officers. Jewish victims are largely off-screen, mentioned in the abstract–if at all. The film even suggests, falsely, that Jews provoked Arabs to commit the Hebron massacre of 1929 by not hiring Arab workers, absolving Palestinian Arab leaders who incited the pogrom.
That is certainly how Israeli actress Mili Avital felt upon reading the screenplay. As she related to an Israeli newspaper last year, she had been approached to participate in the film, but refused after reading the screenplay: “…it was so anti-Zionist that I closed it after 20 pages. I read it and there were tears in my eyes…it pains me to read how [Winterbottom] describes the beginning of Zionism from such an extreme point of view.”
