Thor: Ragnarok opens strongly with $121M US at box office
Robust debut is beating the trend of diminishing returns for sequels
Thor: Ragnarok thundered to one of the year's best box-office debuts, opening with an estimated $121 million US in North American theatres.
The robust debut for the third Thor movie was a welcome shot in the arm for Hollywood and theatre owners who have just suffered through a terrible October at the box office.
Thor: Ragnarok also bucked the trend of diminishing returns for sequels. The 2011 Thor debuted with $65.7 million; 2013's Thor: The Dark World opened with $85.7 million.
The big opening cements the unlikely breakthrough of New Zealand director Taika Waititi, who shepherded the $180 million production to Marvel's best reviews since 2008's Iron Man.
The weekend's other new nationwide release was the holiday-themed comedy sequel A Bad Mom's Christmas. It grossed $17 million over the weekend.
