Burt Lancaster, Robert Ryan. This thriller, Ryan's last film, spewed forth a disturbingly different theory about the events that led to the assassination of JFK than that which was concluded in the Warren Commission report. It theorizes that Kenedy's assassination was the result of a joint government-industry-military conspiracy to get rid of him because of his intentions to end U.S. involvement in Vietnam. 1973/color/91 min/PG/widescreen.
