The actor's body was discovered at his home in Marin County, California on Monday (11Aug14) and local authorities are investigating his death as a suicide.
The tragedy has left the Hollywood community in mourning, and the news reached the cast of Bridges' new film The Giver shortly before they unveiled it at the Ziegfeld Theatre in New York City on Monday night.
Bridges, who worked with Williams on 1991 movie The Fisher King, used his speech at the premiere to remember his former co-star, telling the audience at the venue, "I am filled with such mixed emotions tonight. It's very difficult for me to be here with all these emotions and feelings - wonderful, I must say, but as with many elements in life, there is an underbelly, and we're losing a dear, dear friend, Robin Williams. Such a brilliant human being. My heart goes out to his family... I feel Robin coming in now, he says, 'Get on with it, Bridges! On with the show!'"
At the event, movie mogul Harvey Weinstein also took to the stage to say a few words about Williams, telling the crowd, "I promise you, if he were onstage, he'd want the party to continue and continue and continue. He is well missed and well loved, and whatever the circumstances are, he was a giant in our industry and more importantly, a great man."
