I only recently discovered this half hour video of Ron Mueck and his working methods produced by the National Gallery in London. If you're interested in sculpture, whether hyperrealistic or not, it's worth looking at. The photograph is from a 2006-07 exhibition of Mueck's work at the Brooklyn Museum.
