It’s even weirder when you really look into it – Frankenstein is set in the then-present day of the early 1930s, but the next film, Bride of Frankenstein, starts out with Percy Shelley, Mary, and Lord Byron in Switzerland in what must be 1816, and she tells the story from the first film in flashback. Mary Shelley really WAS writing Science Fiction. She then goes on to tell another story set in the same future time period. And then, of course, all the sequels and interlocking monster films have telephones and other such 20th century trappings.
It gets even weirder with the Mummy films. The first Mummy film (which was also written by Balderston! The man was everywhere! He wrote Gaslight, too!He even wrote the play that On a Clear Day You can See Forever was based on. But I digress) stands alone. The follow-up films seem to be wholly unrelated to the first film, and tell sorta the same story, only now with a different mummy - Kharis, in place of Karloff’s Im-ho-Tep – who has his tongue torn out and thus can’t speak. He also, unlike Im-ho-Tep, stays in his wrappings through the entire series, shambling along and not passing for present-day human. Nevertyheless, over the course of four movies, he seeks out the reincarnation of his love, too, as in the first film.
But the time scale! The first one, The Mummy’s Hand, is contemporary, set in 1940, presumably. The second film, The Mummy’s Tomb (1942) takes place thirty years after the first one – so, about 1970, although the world looks a lot like the 1940s. The next one, The Mummy’s Ghost(1943), takes place immediately after, but the hext film, The Mummy’s Curse (1944), takes place twenty five years after these, so about 1995. the world STILL looks like the 1940s, however.
This was followed b y Abbott and Costello Meet the Mummy in 1955. Arguably it’s not the same Mummy – he’s “KhLaris”, not “Kharis” (Costello’s character keeps calling him “Clarence”), and it sure feels like the 1950s, not the late 1990s. In fact, the whole series was showing its age – the supporting actors – Richard Deacon, Michael Ansara – are more familiar to me and other Baby Boomers as Television actors, not film stars. It was the last film Abbott and Costello made for Universal, and the last gasp of the Universal Creature cycle (except for their wholly 1950s franchise, The Creature from the Black Lagoon).
