Playing various ethnicities
I am very old, so I remember white people playing various ethnicities:
Marlon Brando - a Japanese
Rock Hudson - a Native American
Laurence Olivier - a black man (Othello)
and the most ridiculous - Sean Connery playing an Englishman disguised as a Chinese man.
Even as a young kid "I thought this is dumb. Why not hire the actual ethnicities?"
Then and now, I consider Ricardo the one exception. With his class, style, talent, etc., he could play any ethnicity and make it great.
