A documentary drama on a notorious Communist-era state prosecutor and judge is set for general release in the Czech Republic next week. Murderer by Profession: The Suffering of Karel Vaš features a rare interview with Vaš, who was a key player in some of Czechoslovakia’s notorious show trials of the early Communist period and died last year at the age of 96. Among his best-known victims was war hero General Helidor Píka, whose intercession with the Soviet authorities to have Czechoslovak soldiers freed during WWII may well have saved the life of Vaš, who was being held in a Gulag camp. The film is largely the work of historian Pavel Paleček, who wrote, co-directed and produced it. Its makers say they plan to screen the film at schools and to have it shown at festivals.
