Although Infinity Train only aired for four seasons, the creative team planned and outlined eight "books" in total. The season that got the furthest in development was the unproduced Book Five, which was planned as a feature-length film documenting Amelia Hughes' takeover of the Infinity Train.
History[]
During the course of Infinity Train's run, Owen Dennis revealed at a number of points that he wanted to write an Infinity Train film about Amelia's takeover of the train as part of the planned eight "books" of Infinity Train.
The existence, or rather the planned one, of development on Book Five was first publicly hinted at in January 2021, when the Infinity Train crew yearbook was briefly leaked on Instagram. The yearbook included storyboards depicting Amelia tinkering with the Steward, tearing One-One in half, and using the Steward's weapons to fight someone off-screen. At the time, it was assumed these storyboards were from the then-unannounced but heavily rumored Book Four - Duet.
Following the release of Book Four, Owen Dennis confirmed the film had been planned with a fully written script, but was dropped by Cartoon Network due to lacking a "child entry point." He further commented that he still believed it could be greenlit due to how far it got in the process, so long as demand for the show was demonstrated. This led to a number of viral campaigns to demand more seasons of the series, including FinishInfinityTrain. In response to the April 29th campaign, Dennis released a "frame mock-up" of Book Five.
For a considerable amount of time it was believed that Book Five had been completely storyboarded due to the presence of the images in the crew yearbook. Writer Alex Horab later clarified in a 2023 Twitch stream that Book Five only made it to the script phase and the leaked "storyboards" from the yearbook were actually "fake boards" to provide more visual context for the executives when pitching their script.[1]
Known Elements[]
- The storyline would have run parallel to the events of Book Four, offering more context to Amelia and One's brief scenes throughout the season.
- Throughout the series, there has been an unspoken acknowledgment that the entire process the train puts its passengers through is non-consensual and in some ways incredibly violating. This would have been addressed head-on in a confrontation between Amelia and One.[2]
- The film's primary theme was grief, presumably regarding Amelia's reaction to Alrick's death.
- Amelia tearing One in two, thereby creating One-One, would have been depicted.
- Amelia would have been shown traveling the train with a turtle companion.
- In an Instagram AMA, Owen Dennis claimed the turtle's name was "Cork".[3]
- During a Reddit AMA, a fan asked Owen Dennis to make three ridiculous claims about Book 5, with only one being true. Dennis replied that either One, Amelia, or The Cat would have murdered somebody onscreen.
- In an Instagram AMA, Dennis listed the film's subtitle as "Mutiny". While Dennis does not always tell the truth pertaining to fan questions about the series canon, he is generally truthful about production details.

Trivia[]
- According to Lindsay Katai, Book Five and the unfinished Christmas special were part of the "Season 1" order by Cartoon Network. This meant that the writers for this show were only paid for one season's worth of content.[4]
- Humorously, the movie has been referenced in the show's first season. In the finale episode, "The Engine" the first thing that Tulip mentions when confronting Amelia is having watched her memory tape, which she jokingly refers to as Amelia's movie.

And the Christmas special we were brainstorming when we were laid off was to be the final episode of our 'season one' contract. Only after that would we have been able to negotiate 'season two' rates."
