I was shooting a bike chase scene when real police came on road while patrolling and the camera man kept on shooting them. I even did a gunshot at them. The police officers came and enquired me . I explained them confidently and they left without troubling us much. But I love the shot so much that I am going to keep the shot. Whenever you are shooting unexpected things always happen and sometimes it becomes an advantage as well. As filmmakers we should embrace the chaos.
