Why did Trigun Stampede reimagine Trigun instead of retracing it?

Trigun Stampede, produced by the CG studio Orange and directed by Kenji Muto, with Kouji Tajima as concept designer, premiered on January 7, 2023. At Anime Expo 2022, TOHO producer Katsuhiro Takei explained the founding decision: Nightow's original manga and the 1998 anime are seen as masterpiece level experiences, so the team wanted to try something else. Takei came up with 3D CG animation as a way to differentiate the new project from the original adaptation, and approached Orange because he knew they would succeed in bringing it to life.

Director Muto stated the same rule as a creative brief: "Rather than simply tracing the original manga that started 27 years ago, we wanted to define the meaning of creating this work as an entertainment piece in this day and age." Takei, looking back in a later producers' interview, put it more bluntly: he is a fan of the original work and likes the 1998 and 2010 adaptations, and with such a wonderful original work and anime already existing, there is no point in doing the same thing. Nightow, he said, told him to "do whatever you like," which encouraged him to work in his own way. Takei spent about two years thinking about the setting and the story before script and plot work began.

Nightow's own public verdict, given during production, endorsed the method rather than merely tolerating it: the staff were taking elements from his comic and expanding it, rearranging it, restructuring it, redesigning it, and adding depth to it, and once they had taken the whole series in and adapted it, he felt that this is still Trigun. He also stated the audience facing version: "This isn't going to be just a retread of what's already been done in the manga and anime. There might be a different side of Vash, a different perspective we see."
