Today marks six years since Robin Williams passed away. The man was a legend in entertainment.

A new documentary based on his life and career, 'Robin's Wish', is coming soon. It arrives two years after the HBO doc based on the actor, 'Robin Williams: Come Inside My Mind'.

The trailer for 'Robin's Wish' landed online last weekend.

It depicts the final days of Williams' life and his fight against the neurodegenerative disorder Lewy Body Dementia.

The description for the film reads: "An intimate portrait of Robin Williams and his invulnerable spirit, 'Robin's Wish' is the story of what really happened to one of the greatest entertainers of all time - and what his mind was fighting."

The documentary features interviews with many of the actor’s former collaborators.

It will be available on demand and digital from September 1st.
