Star trek ii : the wrath of khan *** (IMAGINAIRE)

I'm curious about the creative process behind integrating the film's themes into a novel. Was it driven by the movie's narrative or the author's own ideas?

The characters faced tough choices that felt very human despite the sci-fi setting. Did that make the story more impactful for others?

Khan is such an iconic villain — I'm interested in whether the author aimed to humanize him or highlight his complexities.
