Johnson confirmed Hasselhoff's involvement in the project Wednesday posting a video of himself over social media speaking with the actor using FaceTime.
"Pleasure to officially welcome the original #Baywatch gangsta himself David Hasselhoff to our movie!," Johnson captioned the post on Instagram. #Baywatch is the most successful TV show of all time and from the day we announced we were turning it into a movie, "The Hoff" has been our greatest supporter."
"I don't know if the world is ready for the both of us, Are you ready?," Johnson asks the 63-year-old in the clip. "C'mon man The Rock and The Hoff I was born ready!," the former Baywatch star responds back.
"I WAS BORN READY!" Pleasure to officially welcome the original #BAYWATCH gangsta himself David Hasselhoff to our movie! #BAYWATCH is the most successful TV show of all time and from the day we announced we were turning it into a movie, "The Hoff" has been our greatest supporter. Especially once he knew our RATED R movie was going to be a combination of AVENGERS meets ANCHORMAN....🌊🖕🏾Hoff's a cool dude who's down to have fun and here's the best part.. He's been training his ass off and gotten in the best shape he's been in in years! (cue slo-mo running and glistening chest hair.. wait, why the f*ck am I even thinking about Hoff's chest hair!?) World get ready.. #RockAndHoff #ThereAintNoBay #WithoutTheHoff 💯👊🏾
