I love the idea that every person has something in them that we can connect to.
Dustin Hoffman once said that he wanted to play Saddam Hussein, after seeing a photo of him playing with his young grandson. The photo made him think that although Saddam was a horrible person he was also a father and grandfather which was something DH could relate to.
Once he made that connection, DH could see himself in the more unsavoury parts of Saddam’s persona.
We’re all connected. We’re all human.
PSH lived this approach. Its why he was so freaking good at presenting characters from the fringes.
