Promising as the idea of Dream Girl is — a comedy of errors that transpires owing to a man's ability to mimic a woman's voice — director Raaj Shaandilyaa says that bringing the story to life was easier said than done. Not only was leading man Ayushmann Khurrana required to convincingly mimic a woman's voice, but he also had to emulate feminine mannerisms without making them look exaggerated.

"Ayushmann was an RJ before, so he knew how to play around with his voice. But to balance that voice with a feminine body language was challenging. [The fear was that] it may look over-the-top. There are sequences in the film where he plays Draupadi, Sita and Radha. It was tricky for Ayushmann to play the part naturally and yet be dramatic enough. He enacted every scene in so many ways and so well that his character looks natural and yet makes you think, 'Kahin ye ladka toh nahin?'"
