Los Angeles - Superhero sequel Avengers: Age of Ultron scored the second biggest North American box office opening of all time but failed to eclipse the record set by its 2012 predecessor, industry estimates showed on Sunday.
The latest big-screen offering based on the iconic Marvel comics characters raked in a staggering $187.7m in its first weekend, figures from box office tracker Exhibitor Relations showed.
However it fell short of surpassing the record $207.4m opening posted by The Avengers three years ago.
