Ynet has learned that the film is to depict Amir's life starting in his childhood and leading up to his assassination of former Prime Minister Yitzhak Rabin.
The film is said to feature Rabin's character as potentially destructive and hazardous to Israel's existence, should he had lived on.
The Committee for Democracy's postcard
The Committee for Democracy is funded by an American millionaire and its members, including right-wing extremists Itamar Ben-Gvir, Noam Federman and Avigdor Eskin, have decided to actively call for Amir's release.
Their action, they said, was prompted by the government's apparent willingness to release Palestinian prisoners with blood on their hands.
The Committee for Democracy intends to send out hundreds of thousands of postcards in the next few days, featuring an image of Amir and a caption reading "A time for peace, a time for reconciliation. A time to free him."
"We don’t need the sanctimonious leftist leaders to preach us morality," Ben-Gvir told Ynet. "Those who are going to release Marwan Barguti should just shut up. We are making a perfectly logical demand... If they are going to free thousands of terrorists next year, than there's no reason he (Amir) can't be home for Passover."
