Transformers One

Transformers One is a 2024 American animated science fiction action film based on Hasbro's Transformers toy line. It was directed by Josh Cooley from a screenplay by Eric Pearson, Andrew Barrer and Gabriel Ferrari, the latter two of whom also conceived the film's story. The film features the voices of Chris Hemsworth, Brian Tyree Henry, Scarlett Johansson, Keegan-Michael Key, Steve Buscemi, Laurence Fishburne, and Jon Hamm. It depicts the origins of Optimus Prime (Hemsworth) and Megatron (Henry).

In March 2015, following the release of Transformers: Age of Extinction (2014), Paramount Pictures tasked Akiva Goldsman to set up a writers' room to create ideas for potential future Transformers films. By May 2015, Barrer and Ferrari had signed on as writers, and they came up with the idea of an animated prequel set on Cybertron. The film was announced in August 2017, and by April 2020, Cooley had been hired to direct. Animation services were provided by Industrial Light & Magic, and the design was primarily influenced by the Generation 1 era and Art Deco. The score was composed by Brian Tyler.
