Radiohead are to provide the soundtrack for a series of short films on mental health which will be broadcast on MTV.
Young British film-makers will be invited to submit films for the slot as part of an awareness project run by the Samaritans with the Department of Health's Read the Signs mental health campaign.
"We spoke to a number of media companies as part of the rebranding exercise last year," said Sarah Nelson, spokeswoman for the Samaritans. "MTV gives a certain amount of airtime to non-commercial causes as part of its pro-social remit, and when they were approached by Read the Signs, they contacted us.
"The aim of the films is to demystify mental health problems. The winning film will reflect the campaign messages we're trying to get across: that talking doesn't mean you're weak."
Phil Selway, of Radiohead, said: "When the biggest killer of young men in the UK is themselves, anything the band can do to draw attention to the issue of emotional health is worthwhile."
The films will be screened across the UK and Republic of Ireland from 5 May during MTV's normal schedule.
