Superheroes continue to defeat their foes at the box office.

Disney’s Thor: The Dark World, earning $US86.1 million ($A91.40 million), dominated the weekend box office as it opened domestically at No.1, according to studio estimates on Sunday.

Starring Australian Chris Hemsworth, the Marvel superhero sequel earned $US109.4 million ($A116.13 million) when it opened internationally last weekend and brought in $US180.1 million ($A191.18 million) globally. Overall, it has grossed $US327 million ($A347.12 million) worldwide.

In limited cinemas Thursday evening, Thor: The Dark World brought in $US7.1 million ($A7.54 million) overnight.

Surpassing the ticket sales of Thor, which scored $65.7 million when it opened in May of 2011, Thor: The Dark World marks a record for a Disney November opening, topping the $70.5 million The Incredibles earned in 2004.

Paramount hidden-camera comedy Jackass Presents: Bad Grandpa held the second-place slot at the box office for the second weekend in a row, earning $US11.3 million ($A12.00 million) during its third weekend, with a domestic total reaching more than $US78 million ($A82.80 million).

Relativity Media’s 3-D animated kiddie flick Free Birds, soared into third place with $11.1 million in its second weekend.

CBS Films’ Last Vegas, featuring an all-star cast including Michael Douglas, Robert De Niro, Morgan Freeman and Kevin Kline, took fourth place in its second weekend.

Last weekend’s box office champ, the sci-fi Ender’s Game, starring Harrison Ford, Asa Butterfield and Viola Davis, dropped to fifth place in its second weekend.

Expanding to 1144 cinemas in its fourth week, possible Oscar contender 12 Years a Slave brought in an impressive $US6.6 million ($A7.01 million) over the weekend at No. 7.
