A good entry in the early prison-drama cycle.Spencer Tracy is good as the cocky inmate.Arthur Byron has an unusual part as the sympathetic warden of Sing Sing.There aren't too many of them in movies.The action sequences in the movie are expertly handled by Curtiz.Bette Davis does a good job in a small part.Louis Calhern is suitably slimy.The ending is typically of the times in which it were made.
