John Cena is on the hunt. The WWE superstar and sometimes-comedic-actor is now putting his action chops to work in the new Transformers film Bumblebee. Cena stars in the film as Burns, an agent of Sector 7, the government agency that deals with the Transformers robots on earth.

Cena spoke with Men’s Journal for his cover story earlier in 2018 about his transition from being a WWE superstar to a Hollywood actor. Cena spoke about honing his acting skills while being a wrestler: “I’m never the person who asks the question, How far do I go?” he says. “I’m like, ‘If we are going, you have to tell me to stop.’”

Bumblebee is a prequel for the Transformers franchise, taking the action back to 1987 to show how the titular robot began his adventures. Hailee Steinfeld stars as Charlie, who befriends Bumblebee in California, while Cena will lead a group of Sector 7 agents looking to track down Transformers.

The most recent trailer is filled with action, and reveals that Cena’s government organization is working alongside some of the bad Transformers—the Decepticons—who are also trying to track down Bumblebee and other Autobots. The film will also have appearances by numerous other Transformers, including the iconic Optimus Prime.

In a new featurette for the film, Cena also spoke about playing with his own Transformers toys when he was a kid and what it meant for him to be part of the new movie. Here’s a look at the behind the scenes video about designing the Transformer characters for Bumblebee:
