Shankar's direct warning to Power Star

Shankar has casted Power Star Srinivasan in his new magnum-opus I, as reported earlier. Power Star will have a major role in this movie alongside Santhanam in the light-hearted scenes of the movie.
Shankar has given strict instructions to Srinivasan to keep his lips sealed whenever anyone asks him about his character or the plot details of I.
Power Star is generally known for his extravagant self-promoting ways and that’s why Shankar has given this direct warning to the actor to keep mum about I.
