[her film 'Black Nativity', inspired by her sister's passing] Within a month of her death, I started writing. Because it was 'Black Nativity' and had to do with a kid questioning faith, it was the right thing for to write at that moment. It saved me. I let it uplift me. That question of 'How do you keep having faith?' became very real to me.. I look at it and say, 'It's very me'. On the other hand, it's the first movie I've made that my kids can go and see.
