In its second weekend at the box office, 'Thor: Ragnarok' managed to once again hold onto to the No. 1 spot. The film earned $18.6 million on Friday, beating out 'Murder on the Orient Express', which earned $10.7 million and comedy sequel 'Daddy’s Home 2', which brought in $10.9 million. Analysts say Thor, which passed $500 million worldwide earlier in the week and has high praise from critics and audiences, should cross $600 million by Monday morning.
