Shooting has only just begun on the new Baywatch film, and Zac Efron and Dwayne Johnson already have the first pictures from the set up on Instagram.
Both stars posted pictures of themselves in their skin-tight costumes from the remake of the classic TV series.
"My character Mitch Buchannon just gave [Zac]'s character Matt Brody the all important beach speech about what it means to have manly 'Alpha balls'," wrote The Rock. "Zac's ad-libbed responses were brilliant!
"Talented and great dude. World get ready to have some fun, 'cause the beach will never be the same again."
Johnson posted a picture from a readthrough of the script yesterday (February 22) - the day that filming began on Horrible Bosses director Seth Gordon's movie.
Johnson's San Andreas co-star Alexandra Daddario, Priyanka Chopra, Ilfenesh Hadera and Jon Bass will also star, with Sports Illustrated swimsuit-model-turned-actress Kelly Rohrbach playing CJ, the lifeguard made famous by Pamela Anderson in the '90s (much to Anderson's displeasure).
Baywatch will premiere in May 2017.
