I knew he was suffering from Alzheimer's and he dropped out of acting. One other thing about SMB. Not only did he say it was the worst FUCKING thing he ever did but him and John Leguizamo would be HAMMERED on set because they couldn't take the husband and wife directors. Makes me want to watch it again just for that little fact to see what parts their buzzed in.
Also, I think he deserved a nod for Roger Rabbit. When I was a kid I thought he was from America because he played it so well. Also, to play off of just nothing for more then half of the movie and make it look like you believe there's a cartoon rabbit there was just amazing.
