Screenwriter Matt Holloway is a fan of Downton Abbey (2010), and jokingly said that Jim Carter (who played the butler Mr. Carson on the show) should voice Cogman. He was shocked when Executive Producer and Director Michael Bay got Carter signed on as Cogman.
Quintessa's design was based on Alpha Q's design in Transformers: Energon (2004) (a humanoid upper body with tentacles for legs), and the Quintesson's facial designs in The Transformers (1984) (a face with a headdress). The headdress incorporates elements of the Autobot and Decepticon insignias, reflecting her role as the Transformers' creator.
Despite his seeming death during Transformers: Dark of the Moon (2011), the Police car Decepticon Barricade returns, and has apparently survived up to the events of this movie, with a completely new design, including a new vehicle mode.
Blenheim Palace was decorated as a Nazi headquarters for the World War II scenes. This caused controversy amongst British war veterans, who protested that the palace was the former residence of war hero Sir Winston Churchill, and did not deserve such treatment. Executive Producer and Director Michael Bay explained that this was part of the movie, and Churchill's grandson Sir Nicholas Soames lambasted the British press for sensationalizing a mere movie scene.
After the release of Transformers: Age of Extinction (2014), a writers' room was set up to plan the franchise's future beyond the main film franchise. Two of the ideas pitched involved the Arthurian myth and World War II. Executive Producer and Director Michael Bay liked them so much that he decided to incorporate them into the script for this movie.
H.M. Submarine Alliance (P147) is an Amphion class (A class) submarine launched for the Royal Navy in 1947. She underwent modernization in 1958 to 1960, and in 1961, was renumbered as S67. In 1968, she grounded on Bembridge Ledge off the coast of the Isle of Wight, but was successfully refloated, and in 1971, she suffered a fatal battery explosion off of Portland. From 1973 to 1979 she served as a static training vessel at H.M.S. Dolphin (a shore base) after which she underwent hull strengthening to allow her to be lifted ashore, and in 1981, she arrived in dry dock in Gosport, Hampshire where she now serves as a museum and a memorial to all Royal Naval Submariners who have died in service.
Peter Cullen, Reno Wilson, and Mark Ryan are the only actors to appear in the first five live-action Transformers movies, with Cullen as Optimus Prime, Wilson playing Frenzy, Mudflap, Brains, Mohawk, and Sqweeks, and Mark Ryan voicing Bumblebee, Jetfire, a military drone operator, Lockdown, and Bulldog.
This movie contains tributes to Transformers Prime (2010): Earth is revealed to be the planet-eating Transformer Unicron. Optimus briefly loses his identity. An ancient breed of Transformer, who can transform into a dragon appears (Predacons, Knights). The final battle is set in the sky, with the Decepticons trying to engage a machine that will destroy the Earth, and the Autobots fighting to stop them.
This was the first movie to be filmed almost entirely with IMAX 3-D cameras with two ARRI Alexa IMAX cameras mounted onto a 3-D rig with an astounding ninety-eight percent of IMAX footage in this movie.
Onslaught's original alternate mode in The Transformers (1984) was an anti-aircraft truck, but this was revised to a Western Star tow truck. His green color is an homage to the Autobot Tow-Line in Transformers: Robots in Disguise (2000), who was a green tow truck.
While shooting in England, Mark Wahlberg spent time at St. Aidan's Church incognito, and made donations. No one knew anything until afterwards. Reverend Father Des McGiven said, "It's great that we had him in for the service, and we appreciate his generosity towards our church."
Part of this movie was shot at Stonehenge. Executive Producer and Director Michael Bay requested to shoot an explosion on the location, but was denied, so he had a set of Stonehenge constructed to shoot the explosion.
The Transformers' creator being Quintessa was based on the Quintessons from The Transformers (1984) (in that show, the Transformers' creators, who resided on the homeworld of Quintessa), but incoporates elements of Solus Prime, a female Transformer god from Transformers Prime (2010).
(At around one hour and one minute) Quintessa gives Optimus Prime the nickname "Nemesis Prime" when he initially turns evil. This is a reference to a character of the same name that is an evil clone of Optimus, which shows up from time to time in the Transformers fiction, either as a piloted mech or a different character entirely.
This movie was shot on a variety of formats, including 16mm film cameras, RED cameras, Executive Producer and Director Michael Bay's custom 8K camera called "The Bayhem", GoPros, and the majority being ARRI Alexa IMAX cameras on a 3-D rig. What resulted was aspect ratios that switched, not just between sequences, but between individual shots in IMAX 1.90:1, Univisium 2.00:1, and 2.28:1. Unfortunately, this happened to be one of the biggest complaints with this movie amongst audiences, as they found the constant back-and-forth framing to be quite jarring.
This is the second Hollywood movie to be shot in Cuba after The Fate of the Furious (2017). Tyrese Gibson played a major role in the first three Transformers movies and in The Fast and the Furious franchise.
(At around two hours and five minutes) The pyramid that got crushed when Cybertron collided with Earth is the pyramid with the Star Harvester on top, which was destroyed by Optimus Prime in Transformers: Revenge of the Fallen (2009).
Laura Haddock (Professor Vivian Wembley) sent her video audition to Executive Producer and Director Michael Bay in the U.S., and he was so impressed, he travelled to London to meet with her to discuss the role. She later received a call from him with an offer for the part.
Bulldog, the Mark IV tank Transformer, is based on the tank transformers Warpath from The Transformers (1984) (a slightly unhinged robot) and Blitzwing from Transformers: Animated (2007) (a robot who wears a helmet and monocle).
(At around one hour and nineteen minutes) Professor Vivian Wembley (Laura Haddock) is a descendant of Merlin (Stanley Tucci). In Arthurian legend, Vivian is the name of the Lady of the Lake, also known as Nimue.
(At around one hour and fifty minutes) The scene where Bumblebee first speaks, Optimus Prime responds by saying he hasn't heard his voice since the fall of Cybertron. However, Bumblebee spoke to Optimus after the final battle in Transformers (2007), asking if he can stay with Sam. He was voiced by Mark Ryan.
Though this movie was successful, grossing over six hundred million dollars worldwide, this is the second-lowest grossing movie of the Transformers franchise. Bumblebee (2018) grossed only four hundred sixty-seven million dollars worldwide.
The opening battle between Arthur's Britons and the Saxon hoard was filmed at Bourne Wood near Farnham, Surrey, England. This same location has been used for the opening battles of Gladiator (2000) and Robin Hood (2010); and television commercials for "Marmite" and "Ikea".
(At around forty minutes) Hound is the second Transformer to mention his dad. After Cade's (Mark Wahlberg's) one way call with Tessa (Nicola Peltz), he says "My dad never called me." The first Transformer to mention his dad was Jetfire in Transformers: Revenge of the Fallen (2009), where he said his father was the first wheel and didn't transform into anything.
(At around seven minutes) In this movie, it is mentioned that Fidel Castro allows Transformers to live in peace in Cuba. Since then, Castro died on November 25, 2016, it implies that this movie was filmed before his death, in the way that there wasn't time to change his mention.
When Megatron first appears, General Morshower (Glenn Morshower) says he recognizes his voice. This might be an inside joke, since Megatron was voiced by Hugo Weaving in the first three movies and subsequently by Frank Welker.
Topspin is the only wrecker that is confirmed to be still alive. Roadbuster's status is unknown, and Leadfoot is dead, as footage of him being hunted by the cemetery wind was shown in Transformers: Age of Extinction (2014).
Bumblebee is now established to have been a central "member" of the First Special Service Force (F.S.S.F.), alternatively known as the "Devil's Brigade". Historically, it was an elite joint American-Canadian special operations unit famous for its role in the Italian and Southern-France Campaigns between 1943 and 1944. The F.S.S.F. was disbanded in December 1944, but its unique legacy continues in modern Canadian and U.S. Special Operations Forces.
(At around forty-two minutes) In an alternate version of this movie, Nitro Zeus tells the guard that his wife is cheating on him, but in another version, he requests the guard to say "Hi" to his wife for him. Interestingly, John DiMaggio did not play Nitro in the first version of this scene. Instead, Steven Barr, the voice of Berserker, played Nitro.
The first Michael Bay movie to be shown in a taller aspect ratio since Bad Boys (1995). Bad Boys (1995) was shot in 1.85:1, while this movie, and the IMAX 3-D version of Transformers: Age of Extinction (2014), has aspect ratio shifts between various sizes, mostly around IMAX 1.90:1 and Univisium 2.00:1.
Earned the biggest shut-out in the history of the Razzie Awards, by receiving ten nominations at the 38th Razzies and failing to take home a single award.

The trivia items below may give away important plot points.
Megatron has a new helmet design, based on his classic bucket-head look from The Transformers (1984). He was originally to have this helmet look in Transformers (2007), but the filmmakers decided it wasn't menacing enough, and passed the head design to Starscream.
(At around two hours and twenty minutes) This is the second Transformers movie in which Megatron loses his right arm to Optimus Prime in the final battle. The first being Transformers: Revenge of the Fallen (2009).
(At around two hours) Sir Edmund Burton (Sir Anthony Hopkins) is killed by Megatron in a reverse role of the way Harold Attinger (Kelsey Grammer) was killed by Optimus Prime in Transformers: Age of Extinction (2014).
(At around fifty-two minutes) Onslaught dies in a way similar to how Ratchet died in Transformers: Age of Extinction (2014). They lost their right legs and they were shot many times and had some of their parts fall off because of it. But while Ratchet died after Lockdown ripped out his spark, Onslaught died after Drift decapitated him. And while Ratchet died over the span of a few minutes, Onslaught died in a few seconds.
