Another major city has fallen -- and it can't get up! Gerard Butler, Aaron Eckhart, and Morgan Freeman survived 2013's Washington, D.C.-set "Olympus Has Fallen" and they're back to watch London bridge go falling down (falling down, falling down) and everything else get blown to bloody bits in the sequel, "London Has Fallen."

Lions Gate just shared the first teaser trailer, along with this synopsis:

The sequel to the worldwide smash hit Olympus Has Fallen begins in London, where the British Prime Minister has passed away under mysterious circumstances. His funeral is a must-attend event for leaders of the western world. But what starts out as the most protected event on earth, turns into a deadly plot to kill the world's most powerful leaders, devastate every known landmark in the British capital, and unleash a terrifying vision of the future. Only three people have any hope of stopping it: the President of the United States, his formidable secret service head (Gerard Butler), and an English MI-6 agent who rightly trusts no one."

Here goes:

So Eckhart is back as the POTUS, with Freeman as the vice president. Angela Bassett and Melissa Leo have also returned, with British actress Charlotte Riley in a new role. The bombs drop January 22, 2016. Will you be there to see them?

Watch the trailer.
