Last week, when a train roared over Colorado mountain tracks leaving behind 40 blazes over a three-mile area, fire officials were puzzled and alarmed. Investigators quickly tracked down the train, which was being used by a crew filming a Steven Seagal movie tentatively titled "Under Siege II." The train apparently shot out sparks as it ran, igniting the dry Colorado tinder. A Warner Brothers spokesperson blamed faulty equipment, but local officials said the film company will get a bill for at least $40,000. The crew will be back in Colorado in September to begin shooting again -- presumably with better locomotives.
