The film also features Ranveer Singh, Priyanka Chopra, Farhan Akhtar and Anil Kapoor, among others.
"I guess I am not insecure as a person. In fact when Zoya offered me this role, she thought I will not take up. Priyanka's role is bigger in the film but I think the film matters (to me). I said yes to Zoya the moment I heard the role," said the actress.
Anushka is currently busy promoting her film PK that features Aamir Khan in the lead. Directed by Rajkumar Hirani, the film also stars Sanjay Dutt, Sushant Singh Rajput, Boman Irani and Saurabh Shukla.
When asked about her character in the film, Anushka says she can't reveal much.
"I had a great time shooting for 'PK'. It was a pleasure working with Raju Hirani (Rajkumar Hirani) and Aamir. I am not allowed to talk much about my character in the film," she said.
The film is set to release Dec 18.
