Ananova:

Nicolas Cage and rapper 50 Cent are to star in a film based on the real life story of a prison boxing coach.

The Dance will be based on a 2003 documentary on Billy 'The Kid' Roth which Cage helped produce, reports Variety

Ex-prizefighter Roth has spent more than 40 years as a volunteer boxing coach in Louisiana state prisons.

Cage will play Roth, while 50 Cent will play an inmate the coach believes has the talent to be a champ - but he is serving a life sentence.l
