Transformers: The Last Knight is in production for quite some time now and director Michael Bay is sharing pieces of the story quite often. From filming locations to Sqweeks, the latest member of Transformers family, the production staff was quite generous.
In the most recent news, the latest casting notice stated that Liam Garrigan (Once Upon a Time) joined the cast to play King Arthur confirming the rumor about the movie involving the Arthurian legend in some way.
It seems like the war between the Decepticons and the Autobots will take place in the scene of historical legends while other present-day cast such as Mark Wahlberg, Josh Duhamel and Tyrese Gibson will return to the movie with new addition like Anthony Hopkins and Laura Haddock (Guardians of the Galaxy).
