A film about the life of blues legend BB King will open in cinemas across the UK on October 15.

BB King: The Life Of Riley is directed and produced by Jon Brewer, who has been given exclusive access to King’s friends, family and colleagues. The movie promises to be a no-holds-barred doc that explores how a black cotton picker from Mississippi turned his life around and battled against the odds (and rampant racism) to become King Of The Blues, performing over 15,000 gigs and selling in excess of 40 million records worldwide to date.

The film is narrated by Morgan Freeman and features contributions from Eric Clapton, Bono, Ringo Starr, Carlos Santana, Bill Wyman, Slash, Bonnie Raitt, Peter Green, Buddy Guy, Ronnie Wood, Bruce Willis and many more.

At 87 years old BB King continues to tour extensively, last playing the UK at The Royal Albert Hall in 2011, joined on stage by Slash, Ronnie Wood, Mick Hucknall, Susan Tedeshi and Derek Trucks in a concert for DVD also directed by Brewer.

To capitalise on all this BB mania, a lavish King boxset has just been released. BB King: The Life Of Riley Original Soundtrack, with songs from the film, follows on October 22.
