( EW.com ) -- Thor : The Dark World debuted mightily atop the domestic box office this weekend , hammering up $ 86.1 million from 3,841 theaters , which gave Disney 's $ 170 million 3-D sequel a blazing $ 22,418 per theater average . Thanks to the Norse superhero 's increased exposure in last year 's mega-smash The Avengers , The Dark World debuted 31 percent higher than 2011â€²s Thor , which earned $ 65.7 million over its first three days in theaters . The film did n't enjoy as big of a boost as Iron Man 3 , which opened with $ 174.1 million , a 34 percent improvement over Iron Man 2 's debut â€ ” and still the best debut of 2013 . Thor : The Dark World earned an `` A- '' CinemaScore grade from audiences , which Disney reports were 62 percent male and 61 percent over the age of 25 . The film earned an unusually low $ 5.3 million of its gross from IMAX screens , though IMAX engagements were only announced on Monday , three days before the The Dark World 's release . Grosses on the international front are much more impressive : The film pulled in another $ 94 million in its second weekend , bringing its international total to $ 240.9 million after 12 days . The original Thor earned $ 268 million overseas , a figure The Dark World will have passed by this time next week . Disney successfully played up the dynamic between Thor ( Chris Hemsworth ) and Loki ( Avengers breakout Tom Hiddleston ) in marketing , and as a result , the movie gave the studio its best ever November opening ahead of The Incredibles , which grossed $ 70.5 million on opening weekend . It had the ninth-best November start overall behind three Twilight films , four Harry Potter films , and Skyfall , which grossed $ 88.4 million on this weekend last year . It 's too early to tell where The Dark World will finish domestically , though it should be able to reach $ 200 million if it plays like Thor , which ultimately earned $ 181 million . EW : Box office update - 'Thor : The Dark World ' tops Friday with $ 31.6 million . According to studio estimates , the rest of the movies in the Top 5 all finished within $ 1.1 million of each other . Do n't be surprised if the rankings get swapped around when final studio figures arrive on Monday afternoon . Paramount 's $ 15 million prank film Jackass Presents : Bad Grandpa laughed up $ 11.3 million this weekend . The film has now earned $ 78.7 million total and it will make close to $ 100 million before its run is over . After its lukewarm debut , Relativity 's Free Birds rose an encouraging 29 percent to $ 11.2 million , giving it a $ 30.2 million after ten days . While that bodes well for the film , Free Birds needs to fly much higher to make back its $ 55 million budget . Last Vegas fell 32 percent to $ 11.1 million for the frame . The CBS Films comedy , which stars Robert DeNiro , Michael Douglas , and Morgan Freeman , has now grossed $ 33.5 million against a slim $ 28 million budget . EW : 'Thor : The Dark World ' comedy exclusive - Loki argues with kids . If only Ender 's Game had a slim budget . The $ 110 million sci-fi adventure continued to underperform this weekend . After topping the chart in its debut , the Asa Butterfield vehicle fell to fifth place , plummeting 62 percent to $ 10.3 million for a disappointing $ 44 million total . 1 . Thor : The Dark World -- $ 86.1 million . 2 . Jackass Presents : Bad Grandpa -- $ 11.3 million . 3 . Free Birds -- $ 11.2 million . 4 . Last Vegas -- $ 11.1 million . 5 . Ender 's Game -- $ 10.3 million . Outside the Top 5 , 12 Years a Slave successfully expanded into wide release . After moving into 1,144 theaters , the harrowing drama pulled in $ 6.6 million total , giving it a fantastic $ 17.3 million total after four weekends and keeping it one of the most buzzed-about Oscar contenders of the season . Richard Curtis ' latest rom-com About Time fared pretty well in its expansion too . Out in 1,200 theaters , the film , which stars Rachel McAdams , grossed $ 5.2 million , and it now has an early $ 6.7 million total after ten days . See the original story at EW.com .
