Morgan Freeman still loves playing the villain so he can explore "those dark places in your psyche".

Playing a good guy is boring in comparison, he thinks.

"I was talking to Bob Hoskins when we were making Unleashed together," explained the veteran actor. "We were talking about the joy of doing bad guys, and he confirmed exactly what I was thinking.

"With bad guys you get to let it all out. All those dark places in your psyche? You can let them go. When you play good guys it's kind of boring. It's one note."
