The explosive teaser trailer has arrived for "London Has Fallen," the sequel to the 2013 action thriller "Olympus Has Fallen."

Directed by Babak Najafi (“Easy Money II: Hard to Kill”), the followup moves the action from Washington, D.C., to London (as you might guess by the title), where the funeral for the British prime minister turns into a massive plot to assassinate the world’s most powerful leaders and destroy every landmark in the city. Only three people have any hope of stopping it: the U.S. president, the head of the Secret Service and an MI-6 agent who trusts no one.

Opening Oct. 2, "London Has Fallen" stars Gerard Butler, Aaron Eckhart, Morgan Freeman, Angela Bassett, Robert Forster, Melissa Leo, Radha Mitchell, Jackie Earle Haley and Sean O’Bryan.
