Will Smith on why he passed on Django Unchained

Here's what he told Empire, "I came really close, it was one of the most amazing screenplays I had ever ever seen. I was in the middle of 'Men In Black 3' and [Tarantino] was ready to go, and I just couldn't sit with him and get through the issues, so I didn't want to hold him up. That thing's going to be ridiculous. It is a genius screenplay."

One of the most amazing screenplays he's ever seen and it was genius, but he passed it up? All I need to know about the guy.
