Shane McCarthy who created the character of Drift in his first iteration in the comics (The Transformers: All Hail Megatron), dislikes the movie incarnation featured here, accusing him of being a racist stereotype. Fans were quick to point out that McCarthy has also used words to imply he's not fond of Drift's development in later comics like The Transformers: More Than Meets the Eye (which he wasn't involved with) that most feel made him a significantly better character, and that Drift's entire original persona was little other than highly stereotypical itself.
Derrick J. Wyatt, the art director of Transformers Animated, is not pleased with the film's take on his character Lockdown.
Fan Nickname: The drones Galvatron uses as his army are commonly referred as Vehicons; The name comes from Beast Machines, in which Megatron directly controlled a group of sparkless husks that have no sentience which were called Vehicons.

No Export for You: The tie-in toy line. With most of the "regular" toys being sold under the Generations series, which only gets a wide release in a select few countries, this is the first movie-based TF toy line that (aside from the simplified, gimmicky figures aimed at small kids) doesn't even see a first-wave release in a lot of places of the world.
Optimus was supposed to have an armor-up scene where he added new weapons to his robot mode. This would have explained why he suddenly gained flight at the end of the movie. His arms do change slightly as he takes the sword inside Lockdown's ship, but the change is so slight that it generally goes unnoticed.
Crosshairs was originally going to be named Smokescreen.
You Look Familiar: Once again, Mark Ryan who has appeared in previous Transformers films, shows up as a different character.
According to Transformers Manager of Global Brand Development Mark Weber at New York Toy Fair 2014, Strafe is named so not because of trademark reasons, but because the film's two-headed design was considered too great a departure from previous Swoop characters.
