Upcoming documentary to explore the hardships of Robin Williams

The upcoming documentary is sure to hit fans of Robin Williams very hard in the feels

Robin's Wish, an upcoming documentary, will feature interviews with the widow and close friends and colleagues of the much-loved actor.

Featuring archived footage of Robin Williams, we will hear from the legend himself.

Robin's Wish will explore the actor's final days and the incurable brain disease he was fighting unbeknownst to him.

Before the Hollywood actor tragically took his own life in August of 2014 he had been misdiagnosed with Parkinson's Disease.

An autopsy would later reveal Williams, in actuality, suffered from Lewy Body Dementia.

The documentary will, for the first time, shed "an entirely new light on the tragedy, beauty and power behind the mind of one of the greatest entertainers of all time."

In a statement, Susan Schneider Williams said: "During the last year of his life, Robin was confronted with anxiety, paranoia, insomnia, scary altered realities and a roller coaster of hope and despair.

"With our medical teams care, we chased a relentless parade of symptoms but with very little gain. It wasnt until after Robins passing, in autopsy, that the source of his terror was revealed: he had diffuse Lewy body disease. It was one of the worst cases medical professionals had seen.

"Armed with the name of a brain disease Id never heard of, I set out on a mission to understand it, and that led me down my unchosen path of advocacy. With invaluable help from leading medical experts,

"I saw that what Robin and I had gone through finally made sense - our experience matched up with the science. And what I discovered along the way was bigger than me, and bigger than Robin. The full story was revealed during the making of this film and it holds the truth that Robin and I had been searching for."

While the release date of September 1 has been announced for Robin's Wish in the US, no Irish release date has been confirmed just yet.
