Thor New Hammer Anticipation is high for Chris Hemsworth's upcoming Thor: Ragnarok, and while there will be updates and additions to the third film in the franchise, I don't think anyone anticipated this. In his latest tease from the Ragnarok set, Hemsworth posted a sneak peek at his new hammer, and to call it a downgrade would be more than kind. The caption reads "chrishemsworth#Thor3, expect big and little changes." Who knows, maybe the God of Thunder just felt like Mjolnir was too big and gaudy, and decided to go with something more grounded.
