Dreamworks Animation put together two animated flicks in 2006 - 'Over The Hedge' (released in June) and 'Flushed' Away. The quality of computer animation has improved greatly over the years but it sure has come at a cost. Flushed Away cost a staggering $149m to produce. How could a film with no live performances cost so much?It's a question that kids won't care about. They'll be more interested in seeing the tale of Roddy St James, a loveable rat who lives his life as a pet.
