Film culture is strong in Bristol. The largest city in the south west of England is home to Aardman Animation and several other long-established production houses, and was traditionally an engine of BBC production; John Boorman once headed the Corporation's mighty Documentary Unit from here. But these are uncertain times. The BBC is retreating to cheaper points of the compass, Aardman are cutting staff numbers, and on the fringes of the Encounters Short Film Festival, Chris Hopewell of Bristol music video producers Collision Films was downbeat about his trade as a traditional starting point for aspiring film makers: "Don't bother," he said. "Music video as a tool for film making has fallen by the wayside under the onslaught of YouTube." The Google Goliath was to be the subject of much debate as the festival progressed.
