Guru G. Mahesh of Abhinaya Yogam, acting research centre, explained about 'zero acting' theory. This means the actor has to first forget about all his original characteristic movements, habits etc. Then he has to get into the role of the 'character' that he has to play. He has to entirely adopt the nature of the role that he is playing. Guru Mahesh also revealed why he rejects certain students. He said that preference is given to outsiders just because of the mindset and has nothing to do with talent or superior acting.
