This is not related to the unreleased Twilight companion book of the same name.
Midnight Sun (localized title, originally Taiyou no Uta or Song of the Sun) is a 2006 film directed by Norihiro Koizumi, and starring Japanese singer/songwriter YUI. It helped to launch YUI's career and was screened at the Cannes Film Festival when it was released.
Kaoru Amane is a typical female high school student. Every morning, she stares wistfully out her window at Koji the cute surfer boy at the bus stop across the street, and dreams of meeting him one day. Too bad that if she went out to see him, the sunlight would kill her.
You see, Kaoru suffers from Xeroderma Pigmentosum, which is most easily explained as an allergy to sunlight. Thanks to her watchful parents and understanding friend, she's avoided the worst, but still has to stay inside all day (which does wonders for her social life). To get through it all, she sings and plays guitar at the local train station every night, returning before sunrise. And wouldn't you know it, she just happens to run into her mystery surfer boy.
The film has been adapted into a Japanese TV drama, manga, and musical. The musical is famous for having Girls' Generation's leader Taeyeon starring as Kaoru.
A remake starring Bella Thorne was released in cinemas in March of 2018, this movie was the first ever movie lead role for Patrick Schwarzenegger, son of veteran actor Arnold Schwarzenegger.
Tropes associated with Midnight Sun:
- Award-Bait Song: "Goodbye Days", which is still YUI's biggest hit to date. It's a subversion, though: She spends the whole movie writing it, and an orchestral version is used in the background throughout the film as opposed to only the end credits.
- Bittersweet Ending: Kaoru dies, but her CD is finally released.
- Bury Your Disabled: Kaoru, from seems to be implied, is a Type 1 example, given that life-threatening complications can arise from neurological problems
- Floral Motifs: Koaru and sunflowers, the latter which seem to symbolize hope and happiness.
- The Hero Dies: Kaoru at the end of the film. In the musical, she lives.
- Ill Girl: Kaoru, who, as the description states, has xeroderma pigmentosum, thus she's rather nocturnal. Unfortunately, later in the film, her condition starts to get worse.
- Manic Pixie Dream Girl: Kaoru, however, she's also a tragic example.
- Odd Couple: Kaoru and Koji, though, this is more due to circumstances, as the former can go only go out at night, while the latter can go out whenever.
- Silence Is Golden: The entry under Wham Shot below is completely silent, further accentuating its power.
- Shown Their Work: Xeroderma pigmentosum can come with neurological problems, the which Kaoru starts to display before she dies.
- The Shut-In: Kaoru, due to her condition.
- Wham Shot: At the end of the film, we see a shot of sunflowers, but it pans out to show Kaoru dead, with her coffin filled with sunflowers.
Tropes associated with the 2018 remake:
- Bittersweet Ending: Katie finally gets to live out the dream she had by riding on Charlies boat with him in the sunlight, but passes away offscreen some time later. Her song however, has gotten major hits.
- Ill Girl: As per the original, Katies disease starts to worsen after being exposed to the sun for a while.
- Your Days Are Numbered: After being exposed to the sun for a few seconds, Katie learns her brain is contracting and theres only a short time left before she dies.
