How big was the film's three-day opening? Well, the latest Thor episode, boosted by strong reviews and the self-mocking humor of Chris Hemsworth as the powerful Norse god (with Cate Blanchett as Hela, goddess of death), netted more than seven times the take of last week's leader, Lionsgate's Jigsaw.

That movie, which has police investigating a string of horrific murders carried out in the style of supposedly long-dead killer 'Jigsaw,' dropped this weekend to third place at $6.7 million, according to website Exhibitor Relations.

In second was A Bad Mom's Christmas, from STX Entertainment, at $17 million. The comedy stars three actors - Mila Kunis, Kristen Bell and Kathryn Hahn - whose plans change when their mothers (Christine Baranski, Cheryl Hines and Susan Sarandon) drop in unexpectedly for the holidays.

In fourth position was Lionsgate's Boo 2! A Madea Halloween at $4.7 million. The light comedy has actor/director Tyler Perry and buddies heading to a campground which - surprise! - turns out to be haunted.
