  • Till the End of the Moon is the second TV drama produced by Otter Studios, which was originally set up for dangai/BL drama Immortality (皓衣行). It's rumored that Luo Yunxi was tagged to the project since the start
  • A big part of the core creative team also worked on Immortality. And a lot of the Immortality team came from Ashes of Love with Luo Yunxi

    • Immortality only: Screenwriter (He Fang), Costume designer (Huang Wei), Music Director (Guan Dazhou)

    • Immortality & Ashes of Love: Makeup designer (Tsang Ming Fai), B unit director & Action Director (Wang Haiqi), Special Effects Director (Shen Xufei), World Concept company (Hua Tian)

  • The source novel (黑月光拿稳BE剧本) was optioned by Otter before it was complete due to strong early hype around the IP and interesting characters & premise. It's one of the top 10 most-saved web novels of that genre on the JinJiang platform. Its title literally translates to "black moonlight is guaranteed a bad ending screenplay".

  • The screenplay was written for 40 episodes, which was edited into 50 episodes of probably 45 mins each. The original plan (based on governmental records) was to air 34 episodes as part 1 and 16 episodes as part 2. However, the NRTA (Chinese government agency that regulates TV) closed the loophole around airing two seasons back to back early this year, which is why TTEOTM was edited back down to 40 episodes of 55 mins each so that it could air in one go.

  • This is the second time Luo Yunxi and Bai Lu have paired up in a drama. They previously played a couple in modern workplace romance Love is Sweet. Bai Lu expressed interest publicly in pairing up with LYX again in a costume drama numerous times.

  • Part of the creative team came from Huanyu (Bai Lu's management company, aka the production company of Yanxi Palace). This includes award-winning art director Luan Hexin, and the actresses that play Lan An & Yue Fuya).

  • Luo Yunxi was injured right before production began when filming his final scene in Light Chaser Rescue. He got punched in the mouth by a costar which required emergency surgery. This is why production was delayed and Bai Lu had to film her solo scenes first before the official booting ceremony.

  • TTEOTM changed its Chinese title twice. It was originally named 月照千峰为一人 (The moon shines for one person). It was then renamed to 长月无烬 (long moon without Jin/ember, also a pun for without limit or endless), which is the official publication name proposed by fans of the web novel. Right before the booting ceremony, it was renamed 长月烬明 likely for auspicious reasons (especially after the LYX accident and Immortality not airing)

  • Some keen netizens have noticed that if you break apart the characters of its Chinese title, 长月烬明, it becomes 长月火尽日月, which literally means....

    • 长月 (long moon) - how people refer to the drama, in its short form

    • 火 (fire) - Chinese internet lingo for explosive or popular

    • 尽日月 (to the end of sun and moon)

    • (Gotta give one to Chinese people for coming up with auspicious names)

  • Many of the actors in Love is Sweet have minor roles in TTEOTM:

    • Jiang Jun's dad is also Ye Xiwu's dad

    • Yuan Shuai and Jiang Jun's female colleague Qiao Na plays the Moon Goddess

    • Yuan Shuai and Jiang Jun's client plays Ye Xiwu's eldest brother

  • Many of the actors in Ashes of Love have minor roles in TTEOTM:

    • Shuihe (peacock princess) plays the demon god's lieutenant

    • Heavenly Emperor (Runyu's father) plays the King of Sheng

  • Chen Duling (Ye Bingchang / Tian Huan) briefly dated Xichao Wang (who plays Jing Mie, the demon god's other lieutenant). They were apparently introduced by Yu Zheng (boss of Bai Lu's studio). Small world!

Thank you for the summary. 

Thanks. This is really informative and interesting.
