This a scene from Ulagam Sutrum Valiban note the candid nature of the scene actually
Nagesh in the foreground was trying to contact MGR, and MGR should not see Nagesh this is
in the script but the person near MGR saw this (did not know this is a shooting) says to
MGR to look outside someone is calling you. Which MGR in a cinematic way points to other
side and the same time talking to him.
