1941 was really the right year for the MGM version. That studio was at the peak at a technical level, made their J&H almost like a spectacle. It feels really big, as was the custom for all Metro A's featuring top stars, adapted from major novels and plays. Also, Spencer Tracy, who could, on a good day, be genuinely scary when angry, channeled all his rage and personal demons into Hyde. Even now, whenever I watch the film, he gives me the creeps. Later in life he derided the film, felt he was miscast. He was not have be ideal casting for the kindly Dr. Jekyll, but he jumps off the screen as Hyde, but then actors are not always the best judges of their own work.
