Ravi Varma (action director, Agnathavasi, Venky Mama): There are certain sequences that become really difficult because you need to figure out a location, the composition of the sequence, whether the artist is available and how to ensure that they’re comfortable. One such sequence was in Raees, in which Shah Rukh Khan had to jump from one building to another. We thought of shooting it on location, so the first thing we did was to check the distance between the buildings and how safe it was. If the distance between two buildings was too much, we built a small extension or added a pipe. The idea was that the stuntman is attached to a cable and so he runs across that extension and then jumps safely. On the other hand, if the space between buildings is too little, there isn’t enough room to attach a cable. We also checked how old the buildings were because you don’t want the building to break when someone jumps on it.
