For actors they say, there is never an end to the learning curve. On the sets of her new film directed by Vishal Bhardwaj, Anushka Sharma was in for a mighty surprise

After seeing her co-star Pankaj Kapur's convincing performance as a wealthy drunkard, she couldn't believe that the senior actor is a teetotaller in real-life.

Kapur plays the actress' father in the film. A source says, `Kapur plays a flamboyant and rich guy who loves wine and women.

In several sequences, he had to appear sloshed. Being the actor he is, he gave a perfect take every single time.`

Apparently it was only halfway through the film's shoot that Anushka realised that her senior co-star abstains from drinking. The source adds, `Now, she is a fan of Kapur.`
