For veteran actress Shabana Azmi, filmmaker-turned-actor Farhan Akhtar's performance, was pitch-perfect - a title that she would otherwise give only to actors Balraj Sahni and Paresh Rawal.

"Farhan took me by surprise with his performance in 'Rock On'. He was pitch-perfect, " Shabana, who is married to Farhan's father, writer-poet Javed Akhtar, told.

Having said that, the actress clarified that she did not mean to say that Farhan is a perfect actor, but his performance in the film was on a par with renowned actor Balraj Sahni's acting in "Garam Hawa" (1973) as well as with comedian Paresh Rawal's acting in "Sir" (1993).

"Look at the stuff he is made of. I was astonished. His body language is great on screen. We knew he knew how to play a bit of the guitar but didn't know of his craze for rock music, " said Shabana.
