Tycus (1998) (Sensormatic)

Investigative reporter Jake Lowe (Onorati, GOODFELLAS) uncovers the story of a life-time when he is deployed to snoop around the suspicious operations of a mining company, headed by the eccentric tycoon Peter Crawford (Hopper, EDTV). Crawford is using his mining business as a cover-up for the construction of a top secret underground city, which he is building in anticipation of the arrival of Tycus--a gigantic comet that spells disaster for all unlucky enough to live above ground. As the comet hurtles toward Earth, Lowe must reconcile his duty as a reporter with his concern for his family's safety--and possibly save the world--before impact!
