The documentary titled Robin's Wish will tackle the struggle he went through before committing suicide in 2014.
An upcoming documentary film will explore the last days of Robin Williams and his battle with a mysterious disease that led him to commit suicide.
The beloved actor and comedian ended his own life in his own home in Paradise Cay, California, on 11 August 2014 at the age of 63.
Entitled Robin’s Wish, the documentary follows Robin Williams’ widow Susan Schneider Williams, as she tries to find answers behind her husband's unfortunate passing.
It will be released digitally and on-demand on September 1.
Watch the documentary's two-minutes official trailer below.
Robin was diagnosed with Parkinson’s disease weeks before his death.
However, an autopsy report revealed that the diagnosis was not correct. The autopsy report showed that Robin has been suffering from a neurodegenerative disorder Lewy body dementia, the second most common type of progressive dementia next to Alzheimer's disease dementia.
A toxicology report found levodopa (a drug used to treat Parkinson’s disease) antidepressants and caffeine in his system.
Dr. Bruce Miller, director of the Memory and Aging Center at the University of California, explained in the trailer that the Lewy body dementia could cause increased levels of anxiety, self-doubt, and delusions for those who are suffering from the disease.
Robin's widow, Schneider Williams, shared how her late husband suffered from the disease, saying: ‘Nearly every region of his brain was under attack. He experienced himself in disintegrating.’
This statement was echoed by Robin's friend, David E Kelley, who said: "Something was eroding within him."
Director Shawn Levy, who worked with Robin in his final film Night At The Museum: Secret of the Tomb, revealed that he and the crew noticed that something's going on with Robin during filming.
In the trailer, Levy said: "I remember him saying to me, ‘I don’t know what’s going on. I’m not me anymore."
The documentary film is titled Robin's Wish because the late actor ‘wanted to help us all be less afraid,’ his wife revealed adding, ‘that was Robin’s wish.’
In a statement, Schneider Williams said: "We had been discussing what we wanted our legacies to be in life; when it was our time to go, how we wanted to have made people feel. Without missing a beat, Robin said, ‘I want to help people be less afraid."
The emotional trailer ended with Robin saying: "The thing that matters are others – that’s what life is about."
Robin Williams will be forever remembered as one of the best comedians who ever lived.
It's been six years since his passing, but he remained in the hearts of his fans, most of them still unable to accept the sad truth of his death.
One fan tweeted: "Oh my gosh, come September 1st, I’ll be a crying mess. A movie called Robin’s Wish will come out detailing Robin Williams’ life...he’s one of my all tome favorite actors."
