Starting his career in 1970, master documentary editor Steve Weslak, CCE, remembers that working in the tiny film community of the era felt more like being in a garage rock band, rather than the mature industry that we have today. Almost five decades later he is still a vital part of the documentary scene, editing feature docs for HBO, BBC, PBS, NFB and all the major Canadian broadcasters. His editing assignments on international co-productions have taken him around the world, from Sydney, Australia to London, England. Along the way he’s been privileged to work with many outstanding directors such as Ric Bienstock, Alex Gibney, Larry Weinstein and Barbara Willis Sweete.
