Avengers: Age of Ultron hurricanes USA box office

Avengers: Age of Ultron has surpassed the United State and Canada box office through $191.3m (£126.5m), the second-biggest introductory weekend ever in the US.

However the sequel failed to beat the record-breaking opening of the unique Avengers film, which took $207.4m (£137.2m) when it debuted in 2012.  

The weekend's second biggest film, Age of Adaline, took just $6.3m (£4.2m).

The Marvel Disney movie was number one in the UK last weekend and has taken $631.1m (£417.5m) worldwide so far.

Predictors recommended sports events may have affected Age of Ultron's US performance, with Floyd Mayweather and Manny Pacquiao's boxing fight, the Kentucky Derby and NBA playoffs all scheduled over the weekend.

The picture scripts the reappearance of Robert Downey Jr, Scarlett Johansson, Mark Ruffalo and Chris Evans as Iron Man, Black Widow, The Hulk and Captain America.

This period the superhero team - which also includes Chris Hemsworth as Thor and Jeremy Renner as Hawkeye - are battling to save the earth from villainous robot Ultron, voiced by James Spader.

"It was unceasingly going to be intimidating to top the first movie," Exhibitor Relations analyst Jeff Bock told AFP.

"The first film had the novelty of all these superheroes together in one film which we had not seen earlier. Consequently Ultron did not have that benefit."

However Age of Ultron still floored its struggle, with no other film making it past the $10m (£6.6m) abrasion.

Imaginary play The Age of Adaline, in second dwelling, stars Blake Lively as a woman who stops aging after a freak accident.

Blockbuster Furious 7 took additional $6.1m (£4m) in third place with Paul Blart: Mall Cop 2 in fourth and animated film Home rounding out the weekend's top five.
