Chris Martin and Cat Power have united to record a song for a new film by actor/director Zach Braff, NME reports.
Written by Coldplay frontman Martin and performed by Cat Power on lead vocals, the song takes its name from the title of the film, "Wish I Was Here."
The song was missing from the cut of the film premiered at this year's Sundance Film Festival as it wasn't ready in time. Director Braff told Entertainment Weekly that it's "one of the most amazing songs ever."
The soundtrack is also set to include new, original songs from artists including the Shins and Bon Iver. Best known as star of sitcom "Scrubs," Braff directed the 2004 film "Garden State," which is credited with bringing the Shins to a wider audience via its Grammy-winning soundtrack.
Braff, who stars in the film as Aidan Bloom, a struggling actor who reluctantly agrees to home-school his father's two young sons, appealed for the money to make the movie from fans on Kickstarter, a campaign that attracted controversy when it emerged that the project will also receive funding from a New York film company and Braff himself.
