If there is one thing you can say about the Michael Bay Transformers series, it’s that you never know how much crazier they are going to get. The long-running franchise is now entering its fifth installment – subtitled The Last Knight – and it sounds like the director of the madcap action classic Bad Boys II has prepared something suitably wacky for a series about cars turning into robots.

King Arthur has been added as a character for this newest installment. Yes, Optimus Prime will be enlisting the aid of Arthur Pendragon. Liam Garrigan (who has played King Arthur on Once Upon a Time. …What?!?) will be the wielder of Excalibur this time around. Oh, is that not quite nutso enough for you? Well, with every King Arthur you also get a free Merlin! Yes, the master magician will also be appearing in this guaranteed Oscar winner of a film. He’ll be played by Santiago Cabrera (Heroes).

How hot is King Arthur right now? Between Liam Garrigan playing him on Once Upon a Time (that’s still mind-blowing right now) and Charlie Hunnam portraying him in the upcoming King Arthur: Legend of the Sword, it seems like the real estate prices in Camelot are quite appealing. Does this mean we can get a theatrical re-release of Disney’s The Sword in the Stone? If that happens, all this Arthurin’ will be more than worth it.

Plot details about Transformers: The Last Knight are being kept under wraps, but if it doesn’t feature some robots fighting medieval dragons, it will be a big disappointment. Even a robot dragon would suffice. But real dragons? That would be an all-timer. Will Merlin be revealed to be a Quintesson? Is Morgan le Fay actually a time-traveling Blackarachnia? Will Grimlock ever find true love? None of these questions and more will be answered when the world basks in the radiance of Transformers: The Last Knight on June 23.

Weird Al’s “Dare To Be Stupid” makes more and more sense for this franchise as time goes on.
