At one point Muni's character is seen buying a second hand book titled "The Life of Pasteur", the role he would play in his next film, which premiered a month after Dr. Socrates opened.
A man scornfully lists the classic Greek authors Muni reads. One of them is "Erysipelas." This is a skin disease. One screenwriter must have been having a little joke.
Edward McWade is on production lists for the role of "Fisher", but that role was played by Otis Harlan.
Remade as "King of the Underworld," with Kay Francis in the Paul Muni role.
Debut of actress Grace Stafford .
