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

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.
