NEW YORK (AP) — Warner Bros.′ “Black Adam” opened with an estimated $67 million, according to studio estimates Sunday, handing Dwayne Johnson his biggest box-office weekend as a leading man and launching the D.C. Comics character he spent a decade to bring to the big screen. “Black Adam” was a $200-million bid to upset the power balance in a DC Extended Universe dominated by Wonder Woman, Superman and Batman. The $67 million debut fell well shy of that stratosphere even with the considerable draw of Johnson in his first superhero movie. “Ticket to Paradise,” the Bali-set romantic comedy starring Julia Roberts and George Clooney, proved smart counterprogramming. It debuted with $16.3 million, well above recent sales for rom-coms.
