Foo Fighters frontman Dave Grohl has said parts of the band's new film made him feel "incredibly uncomfortable" and were "hard to watch".

Back And Forth is due to be film in cinemas across the UK tonight and follows Grohl's career from Nirvana up to Foo Fighters new album 'Wasting Light'.

It includes drummer Taylor Hawkins near death in 2001 when he spent two days in a coma after taking an overdose of painkillers.
