As Entertainment Weekly reports, the passing initially wasn't confirmed by the actor's publicist, but his rep ultimately issued the following statement:
"Robin Williams passed away this morning. He has been battling severe depression of late. This is a tragic and sudden loss. The family respectfully asks for their privacy as they grieve during this very difficult time."
Known for his roles in "Good Will Hunting," "Mrs. Doubtfire," "Jumanji," "Night at the Museum" and more, Williams left a permanent mark in the movie world as one of the ultimate greats.
According to a press release issued by the Marin County Coronor's office, the Sheriff's office suspects the death to be "suicide due to asphyxia." Fox was also quick to issue an official statement, as the company that will issue the third part of "Night at the Museum" this December.
"There really are no words to describe the loss of Robin Williams. He was immensely talented, a cherished member of our community, and part of the Fox family. Our hearts go out to his family, friends and fans. He will be deeply missed," the statement reads.
The guitar-driven domain was equally shocked, as many prominent rock and metal musicians took on their Twitter pages to express grief and condolences. You can find some of their reactions below.
