While Neill credits the late actor as the "funniest person" he ever worked with, he shares that Williams was also "the saddest person I ever met." "He had fame, he was rich, people loved him, great kids—the world was his oyster. And yet I felt more sorry for him than I can express. He was the loneliest man on a lonely planet," writes the Jurassic Park star, expressing that he remembers Williams seeming "inconsolably solitary, and deeply depressed." Robin Williams.

"Funny stuff just poured out of him. And everybody was in stitches, and when everybody was in stitches, you could see Robin was happy," explained Williams. Williams died by suicide at the age of 63 on Aug. 11, 2014. It was later discovered the actor had Lewy body dementia, the second-most common type of progressive dementia after Alzheimer's disease. After his death, a representative for Williams shared with PEOPLE that "he had been battling severe depression of late."

"It was something that was a daily consideration for him." He continued: "The main thing for me was noticing how he went to great lengths to support himself while he could show up for others. It was clear that he prioritized his mental health throughout most of his life, at least that I experienced with him."
