The photo posted by the OP appears to be BC playing LB when he was a young man, hence I chose a photo of him when he was a similar-looking age.
Regardless, the cliche about Jews having unusually large noses is just an urban myth, and the makers of this film could have easily avoided the furore by not bothering with the prosthetics. What were they actually trying to achieve - did they think the audience might not know who he was without the big nose…? I don’t know why film makers keep doing this - Nicole Kidman looked ridiculous with one as well. The only instance where it has been justified are the films based on the Cyrano de Bergerac story.
