It comes as no surprise that Robin Williams has always been considered the nicest guy by his fans and costars. What may still shock casual fans, however, is that Williams played a wide range of roles during his nearly 40-year career. Not only could he improvise for hours or send viewers into spastic laughter, but he could also play serious, darker roles in films and on television.
Everyone knows about his Oscar-winning turn in Good Will Hunting as an example of his serious talent, but few recall his role in Christopher Nolan's Insomnia or as the lead in the complicated and serious The World According to Garp. Williams played a man obsessed with a family after developing their film, an author with a dark side, an everyman-turned-vigilante after the death of his family, and a host of other roles that turned his nice-guy image on its head. The darkest role isn't an easy choice, but there are several to pick from in his impressive career.
