J.M. may be here to help, but he has his own dark past.     Barnes Walker III   GHOST OF THE NEEDLE marks Barnes Walker III’s second feature acting gig. After playing the physically demanding lead in FREEZ'ER, Barnes was able to take on a supporting role not requiring as much pain and suffering. Even though it may be only his second professional acting job, Barnes Walker III is no stranger to filmmaking. He graduated from NYU's Tisch School of the Arts with a degree in film and has worked on documentaries, features, and commercials. Barnes still doesn't know what he wants to be when he grows up. "I've worked all kinds of jobs lately -writer, film editor, videographer -- so acting is interesting. I can have a different life for a little while."
