Kissing is not very comfortable in our screenplay

Rai added that while onscreen kisses are becoming more common in Bollywood, it will still be a long time before they become the standard.

"A lot of actors have kissed before that movie, they continue to kiss on screen till this very minute, but public display of affection is not that common in Indian culture. Even our actors, it's very rare that actors look comfortable kissing onscreen in our cinema," she said.

"It almost looks like it's a planned moment, just to make much ado about a moment or to excite the audience. It's made into this separate entity from a scene, it's not very comfortable in our screenplay," she added.
