Hollywood was shocked by the weekend death of actor Philip Seymour Hoffman and ET's Rob Marciano got star reaction to the news -- including Kevin Costner, Kevin Bacon and Aaron Paul -- on the sidelines of Sunday's Super Bowl.
Among the Oscar winner's co-stars, peers and friends to also react:
George Clooney: "There are no words. It's just terrible."
Roger Ebert's widow Chaz: "I didn't see Phil at Sundance, but I was talking to someone, saying, 'You know he's here. I heard Roger would like [Hoffman] to play him in a movie, what do you think about that?' We were just talking about that last week," she told The Hollywood Reporter. "Roger and I thought he was just terrific. We thought he was one of the best actors of any age. He was just so versatile, and he was a brilliant, very smart human being."
Robert De Niro: "I'm very, very saddened by the passing of Phil. He was a wonderful actor. This is one of those times where you say, 'This just shouldn't be. He was so young and gifted and had so much going, so much to live for.' My family and I send our deepest condolences to his family."
Nicole Kidman: "What a devastating loss. He was one of the greatest actor's actor of all time. He'd take your breath away, he was so talented. My though and blessings are with Philip Seymour Hoffman's family."
