During the premiere day, celebrities posted on Weibo to promote the drama in support of Luo Yunxi (usually actors only ask for this favor when it's a really important project to their career): Huang Xiaoming, Tan Songyun, Wu Jingyan, Chen Yuqi, Cheng Xiao, Victoria Song, Zhang Ruonan, Huang Xuan, Chen Yao. The most noteworthy ones were Chen Xiao (whose drama was also opening on the same day) and EDG (the esports team that LYX supports)
Sun Zhenni (who plays Pianran) won the role through audition while still in drama school. She was a big fan of Bai Lu and they became close friends during the shoot. She is 1/4 German Jewish through her paternal grandmather.
ShengChen 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).

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)
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)
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.
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).
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.
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.
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".
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 YunxiImmortality: 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)
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.
