Vidya Balan gets into the skin of the character. Demands a smoking ban on the set because she's playing a pregnant woman. Vidya Balan, who is playing the role of a six-month pregnant woman in Sujoy Ghosh's Kahaani, has invoked a no smoking ban on the film sets.

Vidya Balan has demanded a smoking ban around her as she is six months pregnant! The actress has told her director that there cannot be any smoking around her.

Director Sujoy Ghosh isn't complaining, in fact he is rather pleased.

"She's really into the character. So much so that after a while she started freaking us out. She started behaving like an expectant mother and wouldn't let anyone smoke in front of her.. and we were like.. huh? Pregnant!? Who? So I think for Balan once she is mentally there, physical bits are baaye haath ka khel," Ghosh told the tabloid.
