WASHINGTON:- After a smashing start in its first weekend in theaters, “Thor: Ragnarok” thundered to the box office top spot once again this week, taking $56.6 million, according to industry estimates released. The third “Thor” episode, boosted by the self-mocking humor of Chris Hemsworth as the powerful Norse god (alongside Cate Blanchett as Hela, goddess of death), has taken a total of $211.5 million since opening in North American cinemas - with global earnings reaching the $650 million mark. In at number two this weekend was Paramount’s newly released “Daddy’s Home 2,” which took $30 million, according to box office tracker Exhibitor Relations.
