Errol Christie movie has £1.5m backer

We hear on the grapevine that a movie based on the life of Errol Christie and Neville Staple has a £1.5m backer.  Does anybody know more?   One of Errol's boxing students is Hollywood mogul Arnon Milchan - producer of most of Brad Pitt's movies - is he the mystery backer?  Errol's book is still slated for publication in March 2010.  Will this coincide with the movie release?  He's been working with ex-BBC producer Tony McMahon on the book and movie.   All gossip gratefully received.
