However, the road to success was not easy. Aamir Khan has since revealed that the first cut of the film was a disaster. In a 2026 interview, he recalled how his personal security officer, a Mumbai Police officer, bluntly told him after the first screening: "Whatever respect you have earned in the last 25 years, you will lose it with this one film." The film underwent numerous re-cuts and edits over three years before the final, sharp version was perfected. The theatrical trailer finally premiered with Aamir's own Dhobi Ghat in January 2011.
