Everyone probably knows what happened to him by now, so I just wanted to share my personal thoughts.
Robin was one of my all time favorite comedic actors. He was always so manic, and full of witty humor. Growing up he was like the crazy uncle we all wanted. The kind to crack us with dirty jokes and tales of intrigue. The fact that he died from suicide really hits it a lot harder. This could have been prevented. I'm sure his family did all they could, but their had to have been something to keep him from falling that hard.
He has had a successful career, more than most in hollywood could hope for. After the 90's his name kind of dropped out of big box office movies and was replaced with people like Sandler and Stiller. But he still did his stand up, got parts in movies, dabbled in dramas, and had broadway musicals. I just wish I could have had the chance to meet him. The stories he could have told...
To me, he will always be Genie from Aladdin, and Adult Peter Pan.
