Filmmaker Aanand L Rai, who busy shooting his upcoming film Zero, says he will ensure the film will deliver more than what it promises.

Zero features Shah Rukh Khan, Anushka Sharma and Katrina Kaif. About the response received for the film's teaser, Rai says, "I am getting really good feedback. I am trying to give the audience things which are coming from my heart and with Shah Rukh sir, I think, I'm able to achieve that. The kind of fun we all are having while making this film is what I always look for... I still require two months for the completion of the shoot."

The film's actors keep sharing social media posts to keep fans abreast on the fun they are having while shooting the film.  In fact, Shah Rukh recently referred to Katrina as his 'media manager' in a photograph he posted on his Twitter page. 

Zero is a romantic drama written by Himanshu Sharma. It is scheduled for release on December 21. In the last few months, Aanand has produced films including Happy Bhaag Jayegi, Shubh Mangal Saavdhan and Mukkabaaz, which received a positive response from the audience. "I always wanted to associate myself with those films which could give audience something different," he says.

One of his upcoming co-productions, Manmarziyaan, brings Abhishek Bachchan back to the big screen. "I don't know why people are terming it as his comeback film. He was always there. I think it is good for actors also to take gaps as per their wish. He is a talented actor. I always wanted to collaborate with Abhishek and with this script, we are working together under Anurag Basu's direction," he adds.
