Captain America: Brave New World and Thunderbolts also saw so-so box office returns, with the former earning $415 million globally and the latter taking home $386 million. The lowest-grossing Marvel movie of all time is The Marvels, which just broke even at $206 million globally, with 2012's The Incredible Hulk coming in second at $265 million.

Elsewhere at the box office, “Superman” descended to fourth place with $13 million in its fourth weekend of release. The Warner Bros. and DC Studios adaptation has generated $316 million domestically and more than $502.7 million globally to date.

First Steps has reached a pivotal point in its theatrical run as second-weekend numbers confirm a significant drop after its $117.6 million debut. Early estimates show a decline of more than 60%. The film now faces growing competition from new releases.
