With production continuing on Transformers: The Last Knight in the U.K., a slew of videos have surfaced that tease plenty of new details about this action-packed sequel. We've already seen plenty of behind-the-scenes footage from Transformers 5, including explosions and high-octane action, and we get more where that came from in these latest videos. Director Michael Bay also reveals an intriguing device known as the Room Roll, featuring Mark Wahlberg and Laura Haddock doing a death defying stunt.

The latest of these videos to surface on Facebook features a huge device known as the "Room Roll." This device can actually turn a massive room upside down, with stars Mark Wahlberg and Laura Haddock "going for a ride," as Michael Bay puts it. Both stars are seen hanging on for dear life as the room rotates around them, an experience that Laura Haddock describes as "f---ing weird." Unfortunately, it isn't quite clear where in the story this scene is set, or if there are other scenes that utilize the "Room Roll."

We also have a number of earlier videos that have debuted over the past few weeks on the franchise's Facebook. One of these older videos showcases a London car chase, where a number of vehicles, including the upgraded Bumblebee, are seen speeding through the street. Another video entitled "Epic Journey" offers a glimpse at numerous soldiers climbing up a hill, including Josh Duhamel's Lennox. Director Michael Bay also utilized the Facebook Live feature on the set in a video from this past Thursday, where the director reveals they're in their last few days in the U.K. before moving to Africa.

The franchise's Facebook also unveiled a Starscream video featuring footage from the previous movies, along with another Michael Bay live video which teases that the filmmaker was shooting a medieval battle scene. The director shows the fans some of "his friends," posing with a group of actors in medieval costumes, before revealing that the first teaser trailer will arrive in either November or December. The medieval warriors seen in Michael Bay's live video most likely are part of scenes that involve King Arthur (Liam Garrigan and Merlin (Santiago Cabrera). While we don't know exactly how they fit into the story, it is rumored that Optimus Prime returns to Earth searching for an artifact that ties into King Arthur and Merlin. Hopefully we'll see these characters when the first trailer arrives in a few months.

The cast includes Mark Wahlberg, Isabela Moner, Jerrod Carmichael, Laura Haddock and Anthony Hopkins. Michael Bay directs from a script by Art Marcum, Matt Holloway and Ken Nolan, who were all part of the Transformers franchise writers room, where they came up with numerous ideas for sequels and spinoffs. Paramount has set a June 23, 2017 release date for Transformers: The Last Knight, which will go up against Sony Pictures' comedy Rock That Body, starring Scarlett Johansson and Kate McKinnon.
