HBO is set to debut its film “You Don’t Know Jack” tomorrow night at 9 p.m. The title, a witty word play of a common slang expression, challenges viewers with the proposition that they really do not know Jack “Dr. Death” Kevorkian, one of the most recognizable faces of the 1990s.

Playing Kevorkian becomes Al Pacino. Indeed, viewing an advance copy of the film, I thought that Kevorkian, whose trials I attended from 1996 through 1999, had resumed his activities of hastening death, which he did more than 130 times before he was tried and convicted for the 1998 euthanasia of Tom Youk. Pacino looks, sounds and moves like Kevorkian in a virtuoso performance where the actor completely loses himself.
