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.
Near the beginning of the film, Paul Muni is reading a book at a soda fountain. From the back, he is holding the book between the thumb and fingers of right hand. From the front, he is holding several pages between his thumb and index finger and the rest of the pages between his index finger and his other fingers.
