I don't know what I can add to what others have said more eloquently, except to note that when you saw Pollack's name on a film - as producer, director, or actor - you could be assured of quality, and many times greatness. I count Tootsie (which I wrote about here) and Out of Africa among my all-time favorites, and there were plenty of other notable films on Pollack's resume. He will be greatly missed.
