The search is on to find new ways to document the lives of the homeless – nowhere is this more true than in America, with increasing numbers of people sleeping rough. Sue Mitchell talks to filmmaker, Leonard Manzella, who has risen to the challenge with his award-winning film, Shoeshine Caddie.The film follows a year in the life of 61-year-old African American, Adrian Spears. He certainly stands out in the sleepy Californian town where he makes a living shining shoes: dancing around with his bowler hat, starched shirt and bright red uniform. The film opens as he folds up the cardboard sheets he sleeps on at night and makes his way to the storage unit where he keeps clothes and an iron. Everything he owns is immaculately pressed, and it was partly his quiet dignity which drew Leonard to Adrian, and which resonates throughout the movie.Leonard had thought his days in the movies business were over: he gave up his Hollywood career 30 years ago to retrain as a family therapist and through Adrian’s story he has reclaimed his passion. The BBC Producer, Sue Mitchell, came across Leonard’s film whilst recording with a homeless man living just a few miles away. She was intrigued and began exploring the background to the film and examining why it was proving so popular with audiences.
