Sam Worthington tried to be a real-life action hero Saturday and was arrested. When the star, playing a DEA agent in “Ten” with Arnold Schwarzenegger, was refused entrance to an Atlanta bar for being intoxicated, he allegedly pushed a bouncer, yelling, “I’m a DEA agent!” The bouncer then pepper-sprayed him and called cops, who reportedly arrested him for disorderly conduct. Charges were dropped yesterday when bouncer Jerry Link failed to show in court.
