And the world weeps, as Michael Bay (The Rock, Transformers) has finally determined that he is done, completely with any and all Transformers movies after spending nearly half his directorial life under the hood with Optimus Prime.

Speaking with Fandango, Bay says that The Last Knight will be his final go-around directing a Transformers film:

“These movies that I’ve done, they are massive movies. They take a lot out of you,” Bay said when we asked if he was finally — for real, this time — stepping away from the Transformers franchise. “I’ve done it enough, and I’ve had a great time doing it. I’m going out with a bang on this one, and I feel like you gotta go out while you’re ahead, you know. I think I’ve had a good run, and I’ve got a lot of other movies I want to do.”

The filmmaker seems keen on doing something “more adult” again next:

“I just read a very bloody hit man movie that was a page turner. That seems like a fun one to do. I love doing 13 Hours, I love doing Pain & Gain — I think it’ll be something more serious and more adult, I guess.”

My take: Naturally enough for Bay, he’s said the same thing a few times already: once after Dark of the Moon and again after Age of Extinction. Each movie made roughly one billion at the box office, which means there is plenty of money to have him back. But will he, though?
