Chris Hemsworth's Transformers One Movie Debuts Its Trailer in Space (Yes, Really!): See the Launch

Chris Hemsworth and Brian Tyree Henry are taking the launch of their new movie out of this world. 

The animated adventure Transformers One unveiled its first trailer on Thursday, April 18, with a live-streamed countdown and journey into outer space — reaching a peak at 125,000 feet above Earth after an hour — broadcast on Paramount Pictures’ YouTube channel.

"We're really the first movie trailer to be shot up into space?" says Henry in a clip highlighting the launch. Hemsworth adds, "Yeah, the very first one."

The trailer offers glimpses at the story of “how the most iconic characters in the Transformers universe, Orion Pax and D-16, went from brothers-in-arms to become sworn enemies, Optimus Prime and Megatron,” as its official synopsis teases.

Hemsworth, 40, voices Orion Pax while Henry, 42, voices D-16, both bots on the planet Cybertron who are destined to become giant transformer warriors. “With this movie, the sky's the limit," quipped Hemsworth in a clip teasing the space launch. 

Directed by Josh Cooley, Transformers One also features the voices of Scarlett Johansson as Elita-1, Keegan-Michael Key as B-127 a.k.a. Bumblebee, Jon Hamm as Sentinel Prime, and Laurence Fishburne as Alpha Trion.

Paramount Pictures' most recent installment of the franchise based on Hasbro's Transformers toys was 2023's live-action Transformers: Rise of the Beasts.

Hemsworth takes over as the future leader of the Autobots from iconic voice actor Peter Cullen, whose work has been synonymous with Optimus Prime since the original 1980s animated series.

Producer Lorenzo di Bonaventura told Collider in 2023 that Hemsworth is not “playing, for most of the movie, what we think of as Optimus, Peter Cullen. So it's that transition, and Chris's voice has a timbre that… it’s logical that Peter Cullen would take over that voice.” 

As a voiceover star, Hemsworth has reprised his role as Thor in the Marvel Cinematic Universe's animated series What If...? Henry, the first Black actor to voice Megatron in the Transformers franchise, was also recently announced as the voice of Smokey the Bear. Johansson, 39, meanwhile, is known for her voiceover work across genres, including in Her, The Jungle Book and the Sing movies. 

Transformers One is in theaters Sept. 20.
