Jack Black has posted a video to his Twitter accusing Thor - played by Chris Hemsworth in Taika Waititi's new movie Thor: Ragnarok - of stealing the jam he used in his movie School of Rock.
Jack reckons Thor "Totally bit our style, totally poached our jam, and now they're parading around town like they thought of that", jokingly claiming the Led Zepplin classic as his own. Then he puts out a challenge to Thor for a battle of the jams.
Our very own Taika Waititi, who directed the film, retweeted Jack's post and jokingly threw the blame on Hemsworth - "@chrishemsworth he distinctly said THOR so I guess it's on you bro."
Chris Hemsworth responded on Instagram by calling Jack Black out for also stealing the song, and taking on the battle of the jams challenge: "Let's do it. Your place or mine baby? I'm in."
You can hear the song in the movie's trailer below, which was included since the very first teaser back in 2015. Taika said he didn't have the licensing rights to the song until he showed the trailer to Led Zepplin: "When we had the first cut of the trailer and showed Led Zep they understood how perfect the song was for this character."
Lucky they managed to secure it - it's so epic! Great job Taika.
