The problem for Mark Wahlberg is that Michael Bay has previously threatened to leave the Transformers franchise on numerous occasions, only to then be coaxed back in to direct another installment.
Mark Wahlberg only agreed to be a part of the Transformers universe after working with Michael Bay on Pain & Gain, and when you add in his above comments, if Bay does actually depart the series then it is basically a certainty that Mark Wahlberg will do, too.
Because after playing Cade Yeager in both Transformers: The Last Knight and Transformers: Age Of Extinction he has declared that if Michael Bay decides to leave the franchise then he will follow suit.
Mark Wahlberg has already suggested that he won’t ever have to endure filming action scenes against Transformers again.
