Robin Williams plays a real creepy bad guy.

Everyone is familiar with his role in "One Hour Photo" but give "The Secret Agent" with Bob Hoskins a look. Based on the classic novel "The Secret Agent: A Simple Tale" by Joseph Conrad published in 1907

He plays the supporting role of 'the Professor'. An anarchist bomber in turn of the century England.
The closing scene to the movie still gives me chills!
