 In the scene in which Janet makes breakfast, her son Brett is  watching _Werewolf of London (1935)_ (qv) on the television, and he  and his Uncle Ted argue about werewolf lore. Actually, the lore that  Brett argues that "everyone knows about", such as details about  silver bullets and wolfsbane, comes from  _Wolf Man, The (1941)_ (qv), which Curt Siodmak (qv) totally made  up.
