PHILADELPHIA (CBS) — It’s only the first week in May, but the summer movie season is off and running.

Avengers: Age of Ultron ran away to a huge box office showing over the weekend.

The Marvel Comics-inspired fantasy sequel to The Avengers debuted with an estimated, whopping $188-million.

It’s the second biggest domestic weekend opening in movie history.

And what was the first? Why, its 2012 predecessor, which took in $207-million.

The box office leader of the last four weekends, the action-thriller sequel, Furious 7, fell to third place with a modest $6-million, just behind the weekend’s runner-up, The Age of Adaline.

Overall, strictly because of the performance of Avengers: Age of Ultron, industry-wide totals were well above those of the same weekend last year.
