Filmmaker Anubhav Sinha said that after the failure of his 2011 film 'Ra.One', people stopped answering his calls. "Everything ended...I was criticised a lot that I didn't know how to make a film...I had no work. This continued for five-six years," he added. Anubhav said as a director, he shouldn't have been "enamoured" by Shah Rukh Khan.
