The historical record currently indicates that Julius Rosenberg probably gave the Soviet Union information, and that loyal wife Ethel was a bargaining chip used by brother David Greenglass to avoid prosecution. That's about as much background as one needs to appreciate and enjoy this deeply personal and very moving film about the aftereffects of the Rosenberg executions, and the worn out 'did they/didn't they' arguments are of only peripheral importance. Filled with fascinating interviews with the Rosenberg's children and a surprising number of elderly compatriots as well as some timely and frightening 1950s footage of anti-Communist hysteria, Heir to An Execution is an emotional attempt by director Ivy Meeropol (granddaughter of the convicted 'spies') to come to terms with a dark chapter in her family history. Strongly recommended.
