Sujoy Ghosh saved the actress at the nick of time as she almost fell onto the Metro rail tracks in Kolkata while they shot for 'Kahaani'.

Vidya Balan almost fell on the tracks while shooting for her upcoming release, Kahaani at a Kolkata metro station. Fortunately, the director Sujoy Ghosh came to her rescue and saved her from falling onto the tracks.

Recalling the incident Ghosh says, "When we were shooting we had security guards across the platform. It went pitch perfect, not a single thing out of place.

While we were paying attention, amidst all this, the only person we forgot was Vidya (laughs). But she is an adult. She is supposed to take care of herself. There was a scene where she was running backwards on the platform.

She bumped against a weighing machine. She tripped and was about to fall onto the tracks. Seeing that she was about to fall, we immediately rushed to her. When she acts, she acts and forgets everything else."

Ghosh says, "There was nothing heroic about it. Since I was behind the camera I could see what was going to happen. I just had the quick sight to rush and save her from falling."

So did the incident cause an interruption? The director explains, "Balan is like 'Oh cool I got saved, lets get back on the job.'"

"You take a lot of precautions for other people but you take your own folk for granted. We took the precaution for everybody else. We just forgot Balan," he adds.

He signs off saying, "Kahani was shot in real time. We shot during Durga Puja. When you are shooting in real time, you shoot with real people who don't know what's going on. One of our challenges was to be on our best behaviour."
