A fun twist on the Jekyll and Hyde story. As usual, it's about a scientist cursed with a sinister alter-ego, but the emotional roles are reversed here; Jekyll is a disheveled, depressive overly emotional nut who is searching for the Nietzschean"Higher Man" - a human being of pure logic and reason - and unfortunately finds it in his chemically induced doppelganger, Edward Hyde.
Very nice, for the most part. Paul Massie's Jekyll is a bit middling, to be honest, but his Hyde is fantastic. He's portraying Hyde as an artificially charming, eternally smiling, emotionless serial-killing robot-man who genuinely loves everything he does. He's committing heinous murders not because he's a raging madman, but because he enjoys murdering people. It's a very creepy performance for just how dispassionately he does everything with his plastered on idiot grin.
Also you get Christopher Lee as a dapper 19th Century cad (bounder?) who's nailing Jekyll's wife, which ain't too bad.
