What made Nayanthara cry for 30 minutes?

Arya recently held a private screening of his next production venture, Amarakaaviyam, for his close friends and Nayanthara was among those who attended the screening. We hear Nayanthara wept for 30 minutes after watching the film, which is a love story. She was spotted telling friends that the film rekindled many old memories in her. The film, directed by Jeeva Shankar of Naan fame, has Arya���s brother Sathya in the lead.
Confirming the news, Jeeva Shankar says, ���Nayanthara, who is known to be emotionally strong, was touched by the story. After the screening, she wept for a very long time. In fact, even after getting back home, she wept. Five days after the screening, she called me and said that she could not stop thinking about the film. This is a great compliment for me as making someone laugh and cry is the most difficult part of film making.���
