Sayani Gupta, who made her debut in Hindi cinema with the film 'Margarita With A Straw', says her co-star Kalki Koechlin has been a "massive" support system for her.

“She has been a massive support system. We are very alike in our thinking and have a similar kind of background in theatre. Hence, our approach towards work is also similar," Sayani, who has a role in "Fan" and "Jagga Jasoos", said in a statement.
