Often actors are known to perform stunts to accentuate their performance on screen but to Amitabh Bachchan's amazement, he found an action star in his own director. Big B has found his own action man whom he fondly calls 'Khatron ka Khiladi'.

While shooting for his forthcoming film 'Aarakshan', Amitabh discovered that his director Prakash Jha goes to extreme levels and takes dangerous risks in order to get a perfect scene. Reportedly, on the sets of 'Aarakshan', Prakash Jha sometimes used to stand on the edge of a bridge without support, or on a crane 50 odd feet above the ground. He even went on a ground that was full of people and under a running bulldozer, in order to capture the desired scene.

In the quest of this, he had some close calls. While shooting on the ground, his command to cut the shot wasn't audible to the person who drove the bulldozer and Prakash Jha had an almost fatal encounter but escaped, luckily. Looking at the real action by Prakash, Big B tagged him 'Khatron Ka Khiladi'.
