Ever since Baywatch started moving forward with star Dwayne Johnson, there were rumors that roles had been written for the two stars of the original TV series, David Hasselhoff and Pamela Anderson. Most assumed that Pamela Anderson most likely won't be back, after revealing in August that "no one appreciates the remakes," but we never heard one way or another if David Hasselhoff will return. Last night, Dwayne Johnson shared a video on his Instagram page, revealing that David Hasselhoff is in fact coming aboard. Here's what Dwayne Johnson had to say on his social media page, while teasing some interesting plot details.

"'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"

We already know that Dwayne Johnson is taking over David Hasselhoff's iconic role of Mitch Buchannon, so it remains to be seen who David Hasselhoff will be playing in the movie. He joins a cast that also includes Zac Efron, Alexandra Daddario, Kelly Rohrbach, Ilfenesh Hadera, Priyanka Chopra and Hannibal Buress. We reported yesterday that Dwayne Johnson invited a young cancer patient to the set, when production shifts to Savannah, Georgia.

The story follows a "by-the-book and very serious lifeguard," played by Dwayne Johnson who joins forces with a "young rule-flouting hothead" (Zac Efron) to try and save their beach from environmental destruction by an oil tycoon. Seth Gordon (Horrible Bosses) is directing from a screenplay most recently written by Damian Shannon and Mark Swift (Friday the 13th). Justin Malen (Bad Teacher 2) wrote the original draft of the script, with Dwayne Johnson also producing alongside Beau Flynn and Ivan Reitman.

The original Baywatch series started in 1989 on NBC, but it was cancelled after just one season. The show then came back in 1991 in first-run syndication, with new stars such as Pamela Anderson and Yasmine Bleeth, and it became a massive global sensation, remaining on the air until 2001. On the big screen David Hasselhoff most recently starred in The Devil's Carnival: Alleluia! and Stretch, and last summer, he made an appearance on Syfy's Sharknado 3: Oh Hell No!. Take a look at Dwayne Johnson's video below, where he announces David Hoff's casting.
