Well, here is a tough one.
Actor Pete Postlethwaite has died at age 64. While not a household name, Postlethwaite, was a character actor of great talent who appeared in numerous films and television programs over the years. In 2010, he appeared in in no less than Inception, The Town, and Clash of the Titains. This is only the tip of the iceberg as far as his film work however; his credits also include The Usual Suspects, Romeo + Juliet, The Last of the Mohicans, Alien 3, Hamlet, and The Lost World: Jurrasic Park among others.
I always looked forward to seeing his work, and his death is quite a shock. I had no idea he was ill, let alone near death. May he rest in peace and God be with his family.
