U2 have released a short clip of their new music video/short film which stars actor Woody Harrelson.

The full version of 'Song for Someone' - a track from their most recent album 'Songs of Innocence' - will premiere this Thursday on SundanceTV, but you can watch a brief teaser below.

The promo also stars Harrelson's daughter, Zoe Harrelson, and was directed by Vincent Haycock, who has previously directed videos for Florence & the Machine, Calvin Harris, Paul McCartney and other big names.

The video follows on from the short film 'Every Breaking Wave' - also based on a song from 'Songs of Innocence' - which was directed by Aoife McArdle earlier this year.
