"This news has left me heartbroken. I can only imagine the pain his family feels at this time, and my heart goes out to them, especially Deborah, Michael and Liliana. I spent 10 years of my life studying and admiring one of the most brilliant actors, yes, but more importantly one of the greatest men. Jim had the ability, unbeknownst to him, to make you feel like everything would be alright if he was around. I treasure my memories with him and feel so honored that I was an up close witness to his greatness."
