Zero is actress Anushka Sharma's fourth film with Shah Rukh Khan. She says he is the most giving artiste and that she has done some of her most challenging roles with him. In a social media post on Thursday, Anushka recounted the "beautiful coincidence" that Zero is for her.

"I realised this very recently and I had to put it out. I started my career with you Shah Rukh and it's really beautiful that on my tenth anniversary as an actor, we are releasing our fourth film together," Anushka wrote.
