“Black Adam,” the Dwayne Johnson-fronted DC superhero film, kept its hold on the No. 1 spot at the North American box office in its second weekend in theaters. Down 59% from its launch, “Black Adam” added $27.7 million in ticket sales, bringing its domestic total to $111.1 million. That is according to studio estimates Sunday. Bucking recent romantic comedy trends, moviegoers remained curious about “Ticket to Paradise,” Universal’s Julia Roberts and George Clooney destination romp, which fell only 37% in weekend two to claim second place with $10 million. The horror films “Prey for the Devil,” “Smile” and “Halloween Ends” rounded out the top five.
