There are many, many communities, many ethnic minorities, many civilizations that have been brutalised by others and you have to move on. You cannot perpetually stay in that place of blame, otherwise it's just a downward spiral.

I truly believe slavery is why, as a by-product, we still have a disproportionate amount of black men incarcerated in the USA. It is an extension of that legacy, and that's not going to start to diminish until black people have a new sense of themselves that isn't tied to slavery and feeling inferior. I think the church can be instrumental in that, in terms of repentance, reconciliation and just being more embracing of each other - not just on Sunday, but in life generally.

I know that there is still a lot of bitterness and anger, and arguably justifiably so, when you think about how brutal slavery was and what its brutal legacy still is.

Considering how pervasive interracial marriage is, certainly in American society, it is rare we get to see it depicted on film.
