There was near crisis on the sets of Puri Jagannath’s Bbuddah when actor Sonu Sood, who was shooting with megastar Amitabh Bachchan for the first time, was told to get rough with the legend for a scene.Panic-stricken Sood , 37, simply froze at the thought of acting belligerent with Big B, and that too, on the second day of his shooting with him.“Sonu simply went cold. Every actor who faces the camera with Mr. Bachchan for the first time, goes through some amount of nervousness,” said a witness.The final straw was the moment when Sonu was supposed to push Big B to the ground. Sonu staged a walkout, saying, “Sorry Sir, yeh mujhse nahin hoga (Sorry, I can’t do this),” he said.
