Hollywood continues to mourn the sudden loss of Robin Williams, who passed away earlier this week at the age of 63.

Updated  - Matt Damon's statement:

"Robin brought so much joy into my life and I will carry that joy with me forever. He was such a beautiful man. I was lucky to know him and I will never, ever forget him.

I truly hope people in the media can find it within themselves to give his family some privacy during this horrible time."

Ben Affleck's statement:

"Heartbroken. 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. He made Matt and my dreams come true. 

What do you owe a guy who does that? Everything. 

May you find peace my friend. #RobinWilliams"
