A new video has surfaced that takes us up close to a handful of the vehicles being used for filming of the fifth installment of the Transformers movie franchise, Transformers: The Last Knight.

The video, which comes to us from YouTube channel Seibertron, was recorded on a set located near Detroit and reveals for the first time the vehicle mode for Autobot leader Optimus Prime. He’s set to be a 5700 XE truck from Western Star in the latest movie.

The other Transformers included in the video are:

The new movie isn’t slated to hit theaters until June 23, 2017. It’s set to star a few returning human characters as well, including Mark Wahlberg and Josh Duhamel.

Director Michael Bay has released a surprising amount of detail on the characters, including some concept art, which is unusual considering we’re still almost a year out from the release. It may hint that there’s failing interest in the franchise which has tended to focus on showiness rather than substance for previous installments. Considering Bay directed all of those, it’s likely we’re in for more of the same with the latest.
