A young black boy deemed suspicious for wearing a hoodie. A black head of state depicted as a primate. Extremist political parties masking bigotry behind nationalism. Google the word "racism" and you'll find a vast array of news items showing that this most basic form of bigotry is alive and well.
There have been many films big and small which have addressed the subject. But only one comes to mind with racism as an actual character: the controversial drama "White Dog," directed by Samuel Fuller, based on the novel by Romain Gary.
