The band, fronted by singer Karen O, have been frequent collaborators with Jonze.

But his relationship with the group's free-spirited leader goes further, as the pair were dating. Despite breaking up in 2005, they've stayed close and O performed many of the songs on the Wild Things soundtrack.

"I got involved because of Spike -  I guess there is a child-like innocence about my music or my persona that he always just kind of dialed into," she's said.

"So I guess he thought I should make music for Where the Wild Things Are and I assembled a group of mostly rock musicians to help out."
