- Enforced Method Acting: On the "Naruto to Boruto The Live 2019" event, voice actress Nana Mizuki (Hinata) revealed that between recording sessions she would deliberately sit as far as possible from Junko Takeuchi (Naruto), mimicking how Hinata looked upon Naruto from the distance, and before the recording sessions of the final scenes she started sitting right next to Takeuchi, feeling both nervous and happy for it, in order to help convey Hinata's emotions when she finally gets to be with Naruto.
- Fan Nickname: Due to the fact that he tries to steal Hinata away from Naruto and generally behaving like a PG-13 version of a Netorare Villain Protagonist, a few fans and PixIv artists have started calling Toneri "Netori". The fact that Toneri's name can easily anagrammed to "Netori" probably helps too.
- To elaborate: "Netori" is a type of Japanese erotic fiction in which the protagonist tries (and usually succeeds) in winning over a girl from someone who is unworthy of her (abusive, neglectful, stupid etc). Since Toneri sees himself as superior and try to win Hinata from Naruto, a guy whom he thinks is inferior to him, the nickname fits him perfectly.
- Promoted Fanboy: Jun Fukuyama (Toneri) stated that he was a fan of the Naruto manga, and he was excited to be a part of Naruto's final story.
- Reality Subtext: Kishimoto stated in this interview that he got the idea of the red scarf Hinata knits for Naruto from one that his wife made for him once.
- Self-Adaptation: Kishimoto has repeatedly stated that he decided on Naruto/Hinata being the main Official Couple since the early stages of the manga, but he never intended to write the actual story of how they became a couple, because writing romance doesn't come naturally to him. However, when he got the proposal and draft script for the movie, he stated that he thought it was great and it was a movie he wanted to see, as it was a chance to include romance, which he avoided showing in the manga. He created the character designs and joined the writing team as chief story supervisor to create the final script so that this movie was included in the canon of the manga, rather than it being a Non-Serial Movie like all of the previous movies in the franchise. Director Tsuneo Kobayashi confirmed that Kishimoto checked the script and revised it and even gave him advice on how to make the story better. He even personally wrote some of the important lines regarding the red scarf, because it was based on the one his wife knitted for him once.
- Talking to Himself: Averted in the Japanese version, Played Straight in the English dub. Maile Flanagan (Naruto and Boruto) and Stephanie Sheh (Hinata and Himawari) during The Stinger.
