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. It grossed $17 million over the weekend.
