Kubrick's family and many critics felt that his Jewish ancestry may have contributed to his worldview and aspects of his films. After his death, both his daughter and wife stated that he was not religious, but "did not deny his Jewishness, not at all". His daughter noted that he wanted to make a film about the Holocaust, the "Aryan Papers", having spent years researching the subject. Most of Kubrick's friends and early photography and film collaborators were Jewish, and his first two marriages were to daughters of recent Jewish immigrants from Europe. British screenwriter Frederic Raphael, who worked closely with Kubrick in his final years, believes that the originality of Kubrick's films was partly because he "had a (Jewish?) respect for scholars". He declared that it was "absurd to try to understand Stanley Kubrick without reckoning on Jewishness as a fundamental aspect of his mentality".
