Ágætis byrjun
"Untitled #4", as well as "Svefn-g-englar" and the title track from "Ágætis byrjun" and a video backdrop used during a Sigur Rós concert in Los Angeles, are featured in the film "Vanilla Sky". This was the first case of the band licensing their music for a movie; Jónsi allowed for it in part "because he thought the idea of Tom Cruise acting over their music was 'funny'".
