No. What's done is done and the scenes actually serve as good examples of racial insensitivity in film (not that the film industry has come all that long of a way).
The fact that actors like Meg Tily (Margaret Chan), Jennifer Tilly (Jennifer Chan), Ben Kingsley (Krishna Bhanji), Chloe Bennet (Chloe Wang) had to change their 'foreign' names shows how much race still matters in our society.
Yes - these are clear cut examples
No - many actors adopted stage names, not just those from ethnic/racial minority backgrounds
