Imagine the following scenario. Dianne Bell is a world-famous and widely-praised actress. LMK Studios is producing
a Wild West themed movie, set in 19th century America, in which the main villain is a wealthy American businessman and senator. Dianne applies to play the role of the villain, but is turned away on the basis of her sex. LMK Studios claims that it would be historically inaccurate for a female to be a wealthy businessman or politician. Assume this is correct. Has LMK Studios discriminated against Dianne? If so, are any defences available to them?
