William Faulkner wrote a book called Sanctuary, then wrote a sequel called Requiem for a Nun - but instead of another novel, the sequel was a play! The latest season of the popular television show Buffy the Vampire Slayer isn’t on TV at all - it’s a comic book.
What are some other examples of sequels that change medium from the original? Is there a book that’s a sequel to a movie? A movie that’s a sequel to an unfilmed book? And so on?
Yes, but this is an adaptation of the original story, not a continuation- the Dark Tower saga has already been completed.
Besides the original six movies, other segments of the Star Wars saga have been told in books, and a television series was planned (not sure if that’s still going to be done).
George Pal tried for years to do a sequel film to his version of The Time Machine. Failing, he finally co-wrote (okay, the other guy probably wrote it off Pal’s notes) it with Joe Morhaim as a novel called Time Machine II. Though billed on the cover as a sequel to Wells’ novel, it reads more as a continuation of the film (imho).
nitpick Actually, technically Firefly is a TV show with comic books sequels, and then with a movie sequel, Serenity. The three comics cover the time period between the TV show and the movie.
