Ben Affleck has broken his silence regarding Robin Williams' death. The "heartbroken" actor posted a heartfelt message via his Facebook page Tuesday, less than 24 hours after his 63-year-old Good Will Hunting co-star died of an apparent suicide. "Thanks chief - for your friendship and for what you gave the world. Robin had a ton of love in him. He personally did so much for so many people," the 41-year-old actor wrote. "He made [Matt Damon] and my dreams come true."
