Simbu is very friendly. He expects perfection in everything like Make-up, Stunt sequences (Action) etc. Earlier, he too had directed few movies, probably that's the reason behind his expectation for the PERFECTION.While acting, he kind of gives some useful tips.He completely involves himself in the process of filming to make sure that each scene is justified with necessary requirements and each time he appreciates, when the shot/scene (output) really comes out well.
