While shooting for Nicholas Kharkongar's film, 'Mantra', Kalki Koechlin was under the weather. The scenes were being shot late night in freezing Delhi.
The unit thought Kalki would be unable to make it as the scene required her to wear a micro mini skirt and run barefoot on the road. While the unit folk was bundled up in woolies, Kalki stepped out and completed her scenes.
To add to her chagrin, there was a bit of drizzle too. But she was nevertheless a trooper.
