Actor Matt Dillon found himself staring down the barrel of a cop's gun when he was mistaken for a knife-wielding maniac while riding the subway in New York recently. The CRASH star decided to take the C-train to Soho one Friday night and found himself the suspect in a knife attack. He recalls, "A couple of guys were drinking, and there was this other guy who looked a little manic and clearly was not all there. So I thought to myself, 'I'm gonna try and avoid this guy's line of vision.' "At 42nd Street, the train gets detained and an undercover detective drew his gun on me... It turned out that a guy with a knife had run onto the train. One cop thought it was me. "Then they spotted the guy - it was the guy who was sitting across from me."
