Bradley Cooper is facing backlash for his portrayal of Jewish legend Leonard Bernstein in the upcoming biopic "Maestro," with some calling his use of a prosthetic nose "Jewface." The debate has sparked a larger conversation about the use of prosthetics and makeup to portray characters of different races and ethnicities, and Cooper's portrayal is sure to bring this conversation to the forefront. Bernstein's children have come to Cooper's defense, as well as Jewish comedian Sarah Silverman, noting the "long tradition of non-Jews playing Jews."
