Zac Efron and Dwayne Johnson have just started production on a very different type of action movie. Baywatch promises to be an action-filled comic romp, a raunchy, R-rated take on the popular TV series about California lifeguards.

Johnson is starring as Mitch Buchannon (David Hasselhoff's character) along with Zac Efron as Matt Brody (David Charvet's character). Via social media, Johnson shared the first look at the two on set, right after they completed their first scene together.
