Paul Giamatti has paid tribute to his "amazing" Twelve Years A Slave director Steve McQueen.
The Sideways star plays a slave trader in Shame filmmaker Steve's new drama, which also stars Chiwetel Ejiofor, Brad Pitt and Michael Fassbender.
Paul told Collider: "He was amazing. He is a really, really interesting guy. The way it was shot, he is a very interesting dude.
"This movie could be really freaky. His whole take on it is to take any kind of modern sensibility off of it and just create a world in which it's completely normal that people get chained up and beaten and sold to each other. He wanted to create a sense in which it's totally normal, so he's not commenting on it, at all."
Paul, whose character is required to manhandle the slaves, admitted: "(Steve) doesn't whitewash, at all. I couldn't believe some of the stuff that I had to do to some of these people."
But he added: "For me, it was actually oddly easy. For the people I was doing it to, I'm sure it was hard. I had to handle these people in weird ways, like they were livestock. These people were remarkable."
