Johnson announced his involvement with the film on Instagram Wednesday where he described the history behind King Kamehameha and the fact that he has been eyeing the role since he started acting.
"Humbled & grateful to begin this once in a lifetime journey," the actor said alongside a screenshot of a news article about "The King."
"King Kamehameha - the legendary King was the first to unite the warring Hawaiian islands - fulfilling the prophecy that surrounded his fabled life since birth and creating the powerful & spiritual 50th state as we know it today," he continued.
"From the day I began my Hollywood career (2001), my dream was to bring this legacy to life.
In Polynesian culture we have a belief, that something isn't done when it's ready... it's done when it's right. The time is right," Johnson said.
Johnson is producing "The King" through his Seven Bucks Productions company with Dany Garcia and Hiram Garcia, Variety reported.
