Dwayne "The Rock" Johnson cheered on his tanned and toned castmates via social media on Sunday, sharing a photo of a table read for the film.
"Like a proud papa silverback, just look at this talented cool/hot #Baywatch cast.. @ilfenator, @alexannadaddario, @zacefron, @priyankachopra, @kellyrohrbach, @thejonbass and some tatted up, bald brown man with a large head," Johnson, 43, wrote.
EXCLUSIVE FIRST LOOK: #BAYWATCH Day 1. My character "Mitch Buchannon" just gave @zacefron's character "Matt Brody" the all important beach speech about what it means to have manly "Alpha balls". 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. #OnSet #BAYWATCH #Day1 #AlphaBalls #NowWhoNeedsMouthToMouth?
He continued, "This squad has been working extremely hard for months for these roles – the time has come – we start shooting TOMORROW. Let's roll and bring the world some beach fun. #BAYWATCH #LifeguardsOnDuty #AndZacHasNiceT---."
In the image, the faux lifeguards sat around a coffee-cup-littered table and laughed as they looked over their scripts. Efron, seated next to Johnson, was wearing a sweatshirt that appeared to read "Bae Watch."

Kelly Rohrbach, who will portray Pamela Anderson's iconic CJ Parker, also shared the image on Instagram, writing, "here we go..."
"We have such a hilarious and cool cast, amazing location, talented crew, writers, director, producers," she wrote. "It's gon' be off the chain. Get ready for a wild ride!"
The film's other leads include Quantico's Priyanka Chopra – who only recently joined the production to play the villain Victoria Leeds – and Alexandra Daddario.
Johnson has been welcoming the beach bums to the cast through Instagram, sharing cute videos with his new castmates in the months since the adaptation was announced.
