US actor and comedian Robin Williams has been found dead, aged 63, in an apparent suicide.
Marin County Police in California said he was pronounced dead at his home shortly after officials responded to an emergency call around noon local time.
Williams was famous for such films as Good Morning Vietnam and Dead Poets Society and won an Oscar for his role in Good Will Hunting.
His publicist said he had been “battling severe depression”.
In the past he had talked, and even joked, about his struggles with alcohol and drugs.
Williams had recently returned to a rehabilitation centre to “fine-tune” his sobriety, the Los Angeles Times reported in July.
“At this time, the Sheriff’s Office Coroner Division suspects the death to be a suicide due to asphyxia, but a comprehensive investigation must be completed before a final determination is made,” police said in a statement.
In a statement, Williams’ wife, Susan Schneider, said she was “utterly heartbroken”.
“On behalf of Robin’s family, we are asking for privacy during our time of profound grief. As he is remembered, it is our hope the focus will not be on Robin’s death, but on the countless moments of joy and laughter he gave to millions.”
Williams had three children from previous marriages.
Born in Chicago, Illinois in 1951, Williams joined the drama club in high school and was accepted into Juilliard School in New York, the prestigious American academy for the arts.
There, he was encouraged by a teacher to pursue comedy.
The actor was first known for his zany portrayal of an alien in the 1970s TV show Mork and Mindy, a character first seen in the sitcom Happy Days.
He was a regular stand-up comedian while continuing to act in such films as Good Morning Vietnam, Dead Poets Society, Mrs Doubtfire and as the voice of the genie in Aladdin.
While many of his roles were in comedies, Williams won the Oscar in 1998 for best supporting actor as a therapist in Good Will Hunting.
