The Son of Frankenstein film was shot in 1939, where two great horror film grandfathers, monster/Boris karloff, and Iag of the vampire Bela Lugosi rendezvous. Who else, of course, is Basil Rathbone, who replaces Colin Clive as DR Frankenstein's son, Frankenstein Jr. Who else? That's Lionel Atwill. Who is he? He is Professor Moriarty in the secret weapon of BR Fortune. It can be said that if you watch BR Fortune, you can get a lot. If you follow Basil Rathbone, you will find a lot of treasure. The film is directed by Rowland V.Lee. He has worked with BR to make novel films adapted from Agatha Christie: love from strangers and the Tower of London Basil Rathbone in this film, and the great MONSTER/Boris karloff round again.
