Dwayne Johnson tweeted that he has signed on to be the voice of Maui the demigod in Disney Animation Studio’s upcoming film “Moana.” 

The Hollywood megastar, who lived in Hawaii when he was a boy, announced the role Wednesday on his official Twitter account.

“Excited to star as ‘Maui’ in Disney’s next big animated musical, MOANA,” Johnson wrote. “Incredible story! **clears throat. #TimeToSing.”

The 42-year-old Johnson, a professional wrestler-turned-actor, is best known for his roles in the “G.I. Joe” and “Fast & Furious” movie franchises. This past summer Johnson had the title role in “Hercules.”  

The studio has not said much about “Moana” but promises it will be a sweeping comedy-adventure about “a spirited teenager on an impossible mission to fulfill her ancestors’ quest.” 

The story takes place in Oceania where Moana sets sail for a fabled island. During her journey, Moana teams up with Maui — her hero — and together they encounter “enormous sea creatures, breathtaking underworlds and ancient folklore,” according to the studio. 

Veteran filmmakers Ron Clements and John Musker, who created “The Little Mermaid,” “The Princess and the Frog” and “Aladdin,” will lead the project.

“Moana” is expected to be in theaters in late 2016.
