Vishal Bharadwaj is very strict about his character portrayals in the films produced by him. The director-producer sees to it that the actor actually learns the skills in reality and not fake it on screen.
If Vishal made Saif Ali Khan learn the UP dialect including the expletives in Omkara the director has made Vidya Balan take driving lessons for Ishqiya. "Vidya was a complete phobic when it came to driving. She has acute road phobia. She was petrified at the thought of driving. The very thought of driving a car would send shivers down her spine. But not anymore! And it is all thanks to Vishal Bharadwaj. Driving a car was something that is completely alien to her. But Vishal saw to it that she mastered the art and now is pretty comfortable manoeuvring her car on the road."
Vidya hasn't stopped thanking Vishal for making her overcome her fears.
