Speaking to Unilad UK, Bay revealed that Steven Spielberg told Bay that he should stop making Transformers movies following the third film, Transformers: Age of Extinction.
Bay’s final entry in the Transformers franchise was the 2017 film Transformers: The Last Knight.
Despite Bay stepping away from the Transformers franchise, the films are continuing on.
Michael Bay’s Transformers films were a hit when the franchise first launched in 2007, but fans quickly turned on the franchise after several sequels.
