Myriad things can be learned from Late NTR especially in the matters of punctuality, discipline and giving respect to deserved people. He always used to stand when producer walked into the sets. Although the producer is many years younger to him, he used to follow that.
He also used to say that if big heroes fail to respect producers, the youngsters cannot learn. At the same time, he also used to say that if the hero of the film respects the producer then entire unit will also respect him.
But these are the days where producer is being treated down by young lasses and juvenile heroes as well. Who will teach them discipline?
