With Bumblebee’s solo film currently shooting, there’s now some news on another famous Autobot who’ll be joining the titular hero in his own spinoff picture.

As the title suggests, yes, Optimus Prime, the most beloved Transformer of all time, will be a part of Bumblebee. The longtime voice of Prime, Peter Cullen confirmed the news when speaking to Ramdeen Productions, giving a simple “Yes” when asked if we’ll hear his famed vocals in Bumblebee. At this stage, of course, we don’t yet know whether Prime will appear simply in a cameo role or whether he’ll have a larger role to play in the film.

So far, the spinoff from the main Transformers franchise has brought in Hailee Steinfeld, John Cena, Pamela Aldon, Stephen Schneider, Jorge Lendeborg Jr., Jason Drucker, Kenneth Choi, Ricardo Hoyos, Abby Quinn, Rachel Crow and Grace Dzienny to fill out its cast.

The current word on Bumblebee reads:

On the run in the year 1987, Bumblebee finds refuge in a junkyard in a small Californian beach town. Charlie (Hailee Steinfeld), on the cusp of turning 18 and trying to find her place in the world, discovers Bumblebee, battled-scarred and broken. When Charlie revives him, she quickly learns this is no ordinary, yellow VW bug.

To be directed by Travis Knight, Bumblebee is set for a December 2018 release.
