Son of Frankenstein (1939)

Wolf von Frankenstein returns to the Baronial manor from the United States with his wife Elsa and son Peter. He not made welcome by the locals who are still terrified of his father's works and the monster he created. The local Burgomaster gives him a sealed briefcase left by his father and inside, Wolf finds his father's scientific notes. At the manor house he meets his father's assistant Igor who has a surprise for him: the monster his father created is still alive, though in some sort of coma. Wolf's initial attempts to re-animate the creature seem to fail but when Peter says he saw a giant in the woods, it appears he's met success. When people are mysteriously killed in the village there is little doubt that the monster is responsible.
