https://www.youtube.com/watch?v=qPHvPXWmSi8- The first pitch for Age of Extinction would have featured a group of former Decepticons (the "Lords of Deception") in a very "Mad Max"-inspired desert setting (with the Twins' heads on chains) that would have caused mayhem in order to occupy the Autobots while a group of humans build a huge transforming base, which would have been named "Galvatron".
- The original concept for Lockdown looked much more like his Animated counterpart.
- Oil Slick was to be in it, too.
- The Dinobots were intended to be the "Guardians of the Allspark" and were supposed to form a combiner named "Dino-Might". Grimlock would have been able to speak.
- Following Dark of the Moon, Hasbro tried to convince Bay to direct a M.A.S.K. movie.
- After Revenge of The Fallen, Tyrese was considered as Roadblock in a G.I. Joe movie (with a brief "you must be confusing me with someone else" reference to his role in the Transformers films), before Dwayne "The Rock" Johnson was cast for Retaliation. He was then considered to be killed off along with Ratchet in that first pitch for AOE.
- Michael Bay was sold on the idea of directing another Transformers film thanks to a single piece of art that featured Optimus Prime riding atop of Grimlock in T-rex mode.
- Hasbro pushed for Lance Henriksen, but didn't have much say in the matter.
- Cade Yeager started out as a character named "Spike", who would have built a transforming motorcycle that would have been granted life by Optimus at the end of the film. This might have later inspired Sqweeks in The Last Knight.
