Grand biopic as only Old Hollywood could do so well. An excellent performance from Edward G. Robinson as Dr. Paul Ehrlich, who works to create a cure for syphilis while battling tuberculosis and his peers' small-mindedness. With direction by the great William Dieterle and a script co-written by John Huston, this is an exceptional film. It's not easy to make a great movie out of what is essentially a medical research story, but they pull it off. Terrific supporting cast including Ruth Gordon, Donald Crisp, Otto Kruger, Donald Meek, Henry O'Neill, Maria Ouspenskaya, Albert Bassermann, Louis Calhern...so many more. Just a great lineup. Pretty daring to make a movie about syphilis at a time when the Production Code was in full effect. Wonderful biopic you should definitely check out.
