Siegfried Carl Alban Rumann, billed as Sig Ruman and Sig Rumann, was a German-American character actor known for his portrayals of pompous and often stereotypically Teutonic officials or villains in more than 100 films.

Lucky Boy is a 1929 American sound part-talkie musical comedy-drama film directed by Norman Taurog and Charles C. Wilson, most notable for starring George Jessel in his first known surviving feature picture. In addition to sequences with audible dialogue or talking sequences, the film features a synchronized musical score, singing and sound effects along with English intertitles. The sound was recorded using the Tiffany-Tone system using RCA Photophone equipment. The film's plot bore strong similarities to that of the hit 1927 film The Jazz Singer, which had originally been intended to star Jessel before Al Jolson took over the role.
