The 1931 stands out above all others! I enjoyed Mary Reilly which was a bit of a twist but it's Fredric March's performance that really makes it memorable! He's so brutal and cruel to Ivy. Mr Hyde was not only beastly in appearance but in character too! March did a terrific job performing the role that made Hyde manacing, primal.. frightening!
