Hans-Joachim Möbis is not the same actor as similarly named
Hans Moebus, who worked in Hollywood from the 1920s to the 1970s, with whom he is often erroneously confused in modern sources. Hans-Joachim Möbis is not known to have worked outside Germany, and continued filming there into the 1940s. There is no documentation as the time or place of his death, so it's likely his life ended as a casualty of World War II.
