Wahlberg played Cade Yeager in both 2014’s Transformers: Age of Extinction and the newly-released Transformers: The Last Knight, but has already made it known that he’s not really interested in continuing to appear in these robotic blockbusters if Bay isn’t part of them.
It’s certainly plausible that if The Last Knight makes a significant profit, Paramount will attempt to bring back Cade Yeager for a future film.
As such, The Last Knight looks to be both Wahlberg’s second robot-blockbuster and his final Transformers movie alike.
Since Transformers: The Last Knight isn’t gaining fantastic reviews from critics, there is a possibility that it might not achieve the type of success that Paramount was looking for.
