We continue our conversation with Oscar-winning editor Paul Hirsch, who has edited two “Mission: Impossible” installments and is one of the greatest editors of all time. In this week’s wide-ranging discussion, topics include his long-standing relationship with Industrial Light & Magic, his thoughts on screen-size, and confirmation that they actually shot a sequence for “Ghost Protocol” where Paula Patton cuts a bad guy open and manually keeps his heart pumping. (Yes, seriously.) You’ll get so much insight into the making of “Ghost Protocol” that you might faint. But don’t faint.
