The original Monsters expanded universe differed from the modern shared universe trend because, unlike Marvel or DC, the Monsters crossovers werent the product of a well-thought-out studio plan. At the time, the Universal crossovers were a bid to breathe new life into a few Universal franchises that had grown stale. For instance, the first Monsters crossover, Frankenstein Meets the Wolf Man, started as a joke one of Universals writers made during a staff lunch. Producer George Waggner decided he'd take the joke seriously.The film proved to be a critical dud, but turned a profit. Hoping to milk any remaining profit from its once popular horror franchises, Universal decided to bring its three biggest icons together: Frankenstein, Dracula, and the Wolf Man. Thus, House of Frankenstein was born. House of Dracula kept the gravy train rolling until Abbott and Costello turned the franchise into a joke. Now that Universal has thrown its hat in the shared universe ring, the studio will want to capitalize on the name recognition of its most famous big screen Monsters team-up. Expect to see a House of Frankenstein remake in the near future as Universal rushes to catch up to the Marvel and DC expanded universe franchises.
