Anushka Sharma seems to be on cloud nine. While her latest release ‘Dil Dhadakne Do’ is doing brisk business, her other film ‘PK’ is minting money in China. An elated Anushka said, “Responsibility is always there. You have to continue to do good work and you have to be different. ‘PK’ has reached this peak because it had a unique idea. It was a unique concept and the film was high on just that. All of us should be proud of crossing the unknown territory, do the kind of business it did and the acceptability beyond everything else.” The makers of ‘PK’ recently threw a party for the film’s success.
