An adaptation of Mohan Sikka's short story 'The Railway Aunty', the film is erotic in nature.
"When we choose a subject like this, there is a greater chance of moving towards obscenity. I am saying again and again that 'B.A. Pass' is not vulgar and I have made the film in a very dignified manner," Bahl said.
Bahl feels that the way he presents the story in the film, "people wouldn't have seen that in Indian cinema".
He also informs that it is easier to adapt a short story into a film compared to a novel.
"A short story has its characters, a plot, which are easy to adapt into a film. While on the other side, picking up a novel and writing a film's screenplay from it is a task in itself," he said.
"So I would suggest that if somebody is going for an adaptation, then go for a short story as it is easier to do," he added.
'B.A. Pass' stars 'Chak De! India' fame actress Shilpa Shukla as Sarika Aunty, a seductress who seduces a small town boy, played by Shadab Kamal.
