To these people, I say: get over it. We could do with a little more diversity round here.
The most successful recent film with a large black cast? '12 Years a Slave'. A movie about black enslavement in the 1800s. Others recent hits? 'The Help', about a group of black maids in the 1960s. There are of course examples of films with black casts that don't follow this trend, but if the film industry continues to predominantly cast black actors into roles which are largely about 'blackness', then it seriously risks pigeon-holing them for being black.
So let's cheer together: DIVERSITY IS NOT SOMETHING TO FEAR.
I was lucky, as a child. I had plenty of film and book characters that I could identify with. Annie, Matilda, Hermione, Jesse from Toy Story... For little black girls, there isn't such a wide variety.
Remember the Clark Doll experiment? You know the one. Black children in the 1940s were given black and white dolls, and asked to identify 'the nice doll', 'the bad doll', 'the doll you would like to play with'. The children overwhelmingly wanted the white doll, and were more likely to assign positive traits to the white doll than the black doll. The experiment proved that without proper racial integration, the black children had developed negative connotations about their skin colour and race.
Again I scream to the skies: DIVERSITY IS NOT SOMETHING TO FEAR.
And in a time when black people are being prominently killed, criminalised and dehumanised, particularly in America, I fully support broader representation of black people in fiction and film. Media coverage of Michael Brown has gone to great lengths to paint him as a thug, almost forgetting that the 18 year old boy was just that, an 18 year old, murdered by policeman Darren Wilson. How about Eric Garner, a man killed in broad daylight by the NYPD? Garner's murder was even filmed (video here - WARNING, POTENTIALLY DISTRESSING), and yet the policemen involved are not being indicted, and instead Garner's petty criminal profile has been under intense media speculation. If these men had been white, would their stories have been different? Quite possibly.
Once more for luck: DIVERSITY IS NOT SOMETHING TO FEAR.
How did we get on to this? Oh yeah, Annie's black now. What's this world coming to?
