Mumbai -- Hera Pheri director, Priyadarshan is all set with his upcoming flick Tezz starring actor Zayed Khan, who feels that the director is too demanding at times. The movies a multi-starrer with industry stalwarts, but Zayed is doing this film with Priyan for the first time. He (Priyadarshan) is a task master. If he gets disinterested in your performance and if the performance is not up to the mark, he'll cancel the whole shoot and he'll say get lost, go find yourself and when you are ready tell me because I don't want to waste my time', which is very unnerving at times, said Zayed. But of course, that brings the best out of you, he added. Zayed says Priyadarshan is one of those rare directors for whom stars drop their attitude. He is a completely old school director who has constantly evolved as a person and as a director with his films.
