It’s a romantic comedy about a death-obsessed rich goth kid (before goth was really a thing) who ends up falling for an eccentric septuagenarian scofflaw.
My old roommate once took a screenwriting class with the UCLA film school teacher who read Colin Higgins’ early draft of the script as a student project. The professor told Higgins that no studio would ever put that story on screen, and even if one did no audience would want to see it. (To his credit the professor later shared this story to his students as a way of warning them to take his advice with a grain of salt.)
