But she is thankful to co-actor Dev Patel for his support while shooting the scene.

Hailing from Bangalore, Tena shifted base to here with the dream of changing into an actor. She says movies had an impact on her life.
"For the longest time, I DID NOT know what I WISHED to do. I USED TO BE clueless. I watched some movies and that i realised nothing moved me as much as movies. After I watch a tragic film, I WILL cry for days. Acting just felt the proper option," said the 25-year-old.
Before entering movies, she worked as a model.
Explaining her move, she said: "I DETERMINED to go into into acting through modelling. It looked like a wiser decision to be in advertisements, which can be 30 seconds long, so that you have a show reel whilst you visit directors versus someone who didn't. I USED TO BE really lucky that the plan worked."
"After modelling, you get used to the camera, lighting. It gave me a way of familiarity," she said.
