Although Arthur C. Clarke's 2010: Odyssey Two
was written as a sequel to the movie version of 2001
rather than the novel version (in which the Monolith was at Saturn rather than Jupiter). And that wasn't even a movie tie-in per se, since the movie 2010
came out years later.
Also, Gary K. Wolf's original novel Who Censored Roger Rabbit?
was set in the (then) present day and depicted the toons as comic strip
characters, but his later sequel Who P-P-P-Plugged Roger Rabbit?
was based on the very different movie version, with the original book dismissed in passing as a dream Jessica had. (Though how a character in the 1940s could have a dream set in the 1980s is beyond me.) If the movie is better known than the book, and it usually is, then it's good business to do a sequel to the movie instead of the book.
