Salman Khan has turned a producer once again with ‘Hero’. The actor-producer apparently had his director on his toes all the time. Sharing his experience, filmmaker Nikhil Advani said, “I had a great script but the most difficult person to handle was Salman. He wanted everything to be bigger. If we would suggest any action sequences, he would say this is good but make it even bigger! Salman is the most difficult person to satisfy.” For those unfamiliar, Nikhil has directed some popular films like ‘D-day’ and ‘Delhi Safari’ prior to directing ‘Hero’.
