Gerard Butler says they are going to try and top Olympus Has Fallen.
Butler is set to reprise the role of his role as secret service agent Mike Banning in London Has Fallen, and they are looking to make it as good as the first.
Speaking to Collider, the actor said: "That ['London Has Fallen'] was one that kind of came out of nowhere. The first one ['Olympus Has Fallen'] was pretty insane and it's the same with this. How do you top that? But that's what we are trying to do right now."
Although Butler, 44, is yet to start filming the movie- which is due out in October next year and also stars Morgan Freeman and Aaron Eckhart - he let slip that the plot will be just as thrilling as the previous instalment.
He said: "It's about a terrorist attack in London and the president is over there because there's a funeral for the British Prime Minister which is part of the plot to get everybody who is anybody to London. Then the s**t hits the fan."
Butler will be back this summer with How To Train Your Dragon 2, which sees him return to voice the role of Stoick.
The movie has already opened at number two at the U.S. box office, taking $50 million over the weekend.
Butler is currently filming Gods of Egypt with Brenton Thwaites and Nikolaj Coster-Waldau.
