Da McFarlane Toys skabte en actionfigur baseret på Black Adam forud for filmens udgivelse, havde Dwayne Johnson en meget specifik anmodning: at gøre ham mere muskuløs. Dette blev afsløret af Todd McFarlane i et nyligt interview, hvor han sagde:
"We had to get approval on 'Black Adam,' and Dwayne Johnson's only comment was — which I think he was right — , 'Can you make me more ripped?'"
Selvom det måske lyder fjollet, var McFarlane enig. Han forklarede:
"The costume itself wasn't showing off his muscles. We were super accurate to the costume, it's just that the costume wasn't showing it off, so he just wanted us to show it off a bit more. We took a little bit of artistic license to do it. I think it was the right move."
