We're switching to Hollywood (1931)

A German reporter visits Hollywood and is escorted through the MGM Studio by a German nobleman, who is working there as an extra. They meet and speak to several actors, primarily Buster Keaton, John Gilbert, Joan Crawford and Heinrich George. Then they meet Adolphe Menjou, who rehearses a long scene in German. A final scene shows stars arriving at a film premiere, including Jean Harlow, Norma Shearer and Wallace Beery.
