Box Office: Thor: The Dark World Slays the Competition and Debuts at No.1, Earns $86.1 Million

Bad Grandpa a very distant second with $11.3 million

No surprise here. Thor: The Dark World was the top choice for moviegoers this weekend, by a mile.

The action-thriller starring Chris Hemsworth, Tom Hiddleston, Natalie Portman and Anthony Hopkins, and the second follow-up to The Avengers, slayed the competition and earned $86.1 million in its opening weekend.

The sequel to the 2011 blockbuster grossed an estimated $7.1 million in Thursday-night previews and Friday-midnight screenings, its studio reported on Friday. Thor: The Dark World debuted much stronger than Thor, which opened the first coveted weekend in May and made $65.7 million, according to Box Office Mojo.

Jackass Presents: Bad Grandpa took the very distant No.2 spot, earning $11.3 million.

The animated kid-friendly flick, Free Birds, took home $11.2 million and landed at No.3.

Last Vegas, starring Michael Douglas, Robert De Niro, Morgan Freeman and Kevin Kline, nabbed the No.4 spot, making $11.1 million.

The No.1 movie last weekend, the star-studded sci-fi ensemble Ender's Game, rounded out the top 5, taking home $10.25 million.
