In 1928 Hollywood, director Leo Andreyev (William Powell) looks through photographs for actors for his next movie. When he comes to the picture of an aged Sergius Alexander (Emil Jannings), he pauses, then tells his assistant (Jack Raymond) to cast the man. Sergius shows up at the Eureka Studio with a horde of other extras and is issued a general's uniform. As he is dressing, another actor complains that his continual head twitching is distracting. Sergius apologizes and explains that it is the result of a great shock he once experienced.
