Shooting the movie Line Walker in the notoriously violent and crime-ridden slums of Brazil proved to be more exciting than expected for star Louis Koo.

“Our film set was guarded by the local police when we were there. But when we had to go into a region which was not accessible to police, we had to rely on the local security forces in that area,” the Hong Kong actor recounted, adding that they heard sounds of a shootout and saw walls riddled with bullet holes, which added to the thrill of filming the spy flick.
