“Thunderbolts” took first place, with $33.1 million from theaters in the U.S. and Canada, according to studio estimates Sunday. Internationally, it added $34 million, bringing its global total to $272.2 million. In just two weekends, the Walt Disney Co. release is already the fourth biggest of the year, globally and domestically.

With no new event pic on the marquee, Marvel Studios' ensemble superhero pic easily stayed No. 1 in its second weekend.

Will "Thunderbolts" endure at the box office? That's the big question surrounding Marvel's latest big budget tentpole.
