Coldplay last night attended the premiere of the new British film they helped to fund.

Directed by Mat Whitecross, who has shot several Coldplay videos including recent single 'Paradise,' Spike Island was screened for the first time last night at the BFI London Film Festival.

Chris Martin revealed that “we had great faith that he’d pull it off” before joking about how much the band had invested in the film, due for release in April 2013:

"12 million pounds. I didn't see evidence of that anywhere. They said it was going to have robots. We've been shafted again.”

Based on an unsigned band’s attempts to get tickets for The Stone Roses’ famous 1990 Widnes gig, Spike Island stars Shameless’ Elliott Tittensor, Hollyoaks’ Nico Mirallegro and Games Of Thrones’ Emilia Clarke.
