Chris Hemsworth Responds To Jack Black's Challenge To A Jam Off

Chris Hemsworth and Jack Black are set to go head-to-head in a 'Jam Off' - whatever that is...

The comedic legend sent the challenge out to the Aussie 'Thor' actor, after accusing Hemsworth of "stealing" Led Zeppelin's huge hit, 'Immigrant Song' for the latest instalment in the franchise, Thor: Ragnarok.

Black claimed that they stole the idea from his film School of Rock, and challenged Hemsworth to a Jam Off via an Instagram post.

Hemsworth responded, admitting to stealing Immigrant Song, but also suggested Black stole it himself for School of Rock.

He also accepted Black's offer of a Jam Off, although he wasn't quite sure what he was signing himself for.
