LONDON: A bus has exploded in central London — but this time it’s only for a movie. City officials on Sunday reassured the public that the explosion was a movie stunt for The Foreigner starring Jackie Chan and Pierce Brosnan. The sight of the bus in flames and the twisted wreckage afterward caused consternation on Twitter from London residents who said the public had not been adequately warned about the stunt. Some complained that children had been frightened by the blast.
