Imagine Dragons have dropped a brand new video this afternoon, and it's probably their most action packed yet.
It stars Dolph Lundgren, a Swedish martial artist who made his debut in the James Bond feature A View To Kill. He also starred opposite Sylvester Stalone as his Russian opponent 'Ivan Drago' in Rocky IV.
You'd have to be pretty brave if you're engaging in some one on one action with him, but lead singer Dan Reynolds seemed up for the challenge.
The video shows Dolph and Dan face off in a boxing match.
The video for Believer was directed by Matt Eastin. He previously worked with the band on their On Top of the World and Roots videos.
