"The title Rockstar can sometimes go against us because when people hear Rockstar, they feel the film will have this guy who will wear a leather jacket, will break the guitar, will create a mess on the stage. Actually the film is about a character, a Jat boy, and whatever happens in his life, he tells the world about it through his songs," Kapoor said.

The actor has strummed the guitar, indulged in head banging, and rocked the stage for the movie, set for release on 11 November. In the movie, Kapoor plays the role of Janardhan or Jordan, an aspiring singer, who goes on to be a popular rockstar.

Kapoor went out of his way to learn how to play the guitar for the film.

"I had no idea how to play the guitar and neither can I sing. But since the character was that of a musician, I felt it was important to learn how to play the guitar because when I would perform on the stage before a large audiences, they would feel truth behind it," he said.

Rockstar, directed by Imtiaz Ali, marks the debut of model Nargis Fakhri.
