According to a Facebook post written by his friend and TV writer-producer Tracy Newman, Santoni died on Saturday morning. He had been “sick for quite a while.”
“Those of you who knew him know how funny he was, what a terrific actor, improviser, performer, etc.,” the post read. “So brilliant. I loved him very much and will miss him terribly. Another great one is gone. I have a lot of wonderful pictures of him, and will post them over the next week.
