'Captain America' bests Mowgli to grab US box-office lead

"Captain America: Civil War," starring Chris Evans, is built around a seemingly foolproof formula: Marvel comics superheroes -- including Iron Man, the Black Widow and the captain himself -- turning against one another in a series of massive fights over whether to submit to the United Nations.

Its first-weekend total was the fifth best ever behind "Star Wars: The Force Awakens," "Jurassic World," "The Avengers" and "Avengers: Age of Ultron".

The film pushed "Jungle Book," in its fourth week, to second position. The adventures of Mowgli and friends had a weekend take of $24.5 million and has taken in $287.6 million since it came out, according to industry tracker Exhibitor Relations.

The romantic comedy "Mother's Day," starring Julia Roberts and Jennifer Aniston, was far back in third place with $11 million but, with the actual Mother's Day falling on Sunday, up from fourth spot.

The film follows several seemingly unconnected people as they come to terms with their mothers.

In fourth was "The Huntsman: Winter's War," a part prequel, part sequel to 2012's "Snow White and the Huntsman," starring Chris Hemsworth, Charlize Theron, Emily Blunt and Jessica Chastain. It took in $3.9 million.

"Keanu," a Warner Bros. comedy starring Keegan-Michael Key and Jordan Peele as gangsters trying to rescue a pet kitten from a drug dealer, netted $3.3 million, about a third its previous weekend's take.

Rounding out the top 10 were:

-- "Zootopia" ($3.2 million)

-- "Barbershop: The Next Cut" ($2.8 million)

-- "The Boss" ($1.9 million) -- "Ratchet and Clank" ($1.5 million)
