"I go so deep into the character that I make myself unwell. It becomes disturbing at times. I have taken training for acting for a year. I can never cry with the help of glycerine. Whenever I cry on screen I cry naturally, if I am happy, I am genuinely happy on screen," Sonam said.
Sonam, who is awaiting the release of her forthcoming film 'Raanjhanaa', says she doesn't mind giving umpteen retakes until her director is satisfied.
"I am a director's actor. If my acting is appreciated, it's because of the director, and if it's not appreciated, it's all again because of the director. I will keep giving them takes till they are convinced," she added.
Directed by Anand L.Rai, 'Raanjhaana' features southern star Dhanush opposite Sonam. It releases on June 21.
