Good point. Logan's World, the sequel to the novel Logan's Run, didn't literally ignore the first book, but very quickly advanced the plot so that the beginning of the sequel more or less synched up with the ending of the movie. Like in about five pages or so . . . .
The same thing happened with Michael Crichton's Jurassic Park: The Lost World, and Pal Gallaco's sequel to The Poseidon Adventure, both of which follow on from the changed movie endings of the originals (Ian Malcolm surviving and the Poseidon still being afloat, when neither was the case in their original novels, respectively.)
