Death Warmed Up (1984, NZL/AUS) C-78m. ** D: David Blyth. Starring Michael Hurst, Margaret Umbers, William Upjohn, Norelle Scott, David Weatherly, Bruno Lawrence. Quite ambitious, not-bad, but ultimately flawed horror thriller about a mad brain surgeon, who has turned most people on an unspecified island into zombies. Young Hurst, who was sort-of hypnotized by the doctor into killing his own parents, comes to the island to get his revenge. Several scenes drag interminably and film seems long despite short running time. Some found this good; judge for yourselves.
