For DreamWorks Animation, last year's Flushed Away unfortunately lived up to its title, draining away millions of dollars from the company's coffers. The film, a joint production with British animators Aardman Studios, reportedly cost more than $140 million to produce and wound up grossing only $64 million domestically. As a result DreamWorks Animation wrote down $109 million on the film for the fourth quarter and reported a $21.3-million loss. That compared with a $63.2-million profit during the comparable quarter a year ago.
