Jackie Chan is filming a movie right now in London and the crew blew up a double-decker bus on the Lambeth Bridge, which sent locals into a panic.
The explosion happened on Sunday morning (February 7) and it was all a coordinated stunt for the upcoming film The Foreigner, which also stars Pierce Brosnan.
There were warning signs around town, but not everybody saw the notices and many people thought a terrorist attack was happening.
“Anyone worried about the exploding bus on Lambeth Bridge just now? It was just for a movie,” one Twitter user wrote with the below video.
