LOS ANGELES, Jan. 12 (UPI) — Dwayne Johnson says there’s “fun” to come with his role as Black Adam.

The 44-year-old actor said in an Instagram post Wednesday that the new DC Comics movies, including his film Shazam, will be hopeful, optimistic and entertaining.

“Had a very cool and strategic meeting with the heads of DC about their entire universe,” Johnson wrote to his 74.8 million followers.

“As a hard core DC fan, to get a real sense of the tonal shifts and developments in these future movies has me fired up. Something we, as DC fans have all been waiting for for a very long time. Hope, optimism & FUN,” he said.

“Even when talking about the most ruthless villain/anti-hero of all time finally coming to life. Prepare yourselves DC Universe. #KneelAtHisFeet #OrGetCrushedByHisBoot #BlackAdam,” the star teased.

Johnson will play Black Adam, an archenemy of Captain Marvel, aka Shazam, in the standalone film Shazam. He told fans in a YouTube Q&A last week that he was drawn to the villain because of the character’s backstory.

“I have loved the role of Black Adam. I love that he starts off as a slave, that he felt like he was wronged,” the actor said.

“I have just loved that backstory. I think that Black Adam has always been, to me, the most intriguing superhero,” he added.

Shazam has yet to announce who will play the titular superhero, but is slated to open in theaters Apr. 5, 2019. Johnson will also star in a movie reboot of Baywatch with Zac Efron and a remake of Jumanji with Karen Gillan.
