A leading daily revealed a false story about the casting of the film. It read , `In 2013, Ekta had pitched the idea to Bebo. She wanted to get Kareena and Emraan Hashmi on board for the film, which was previously titled Badtameez Dil. But it never materialised. Bebo felt that the storyline was way ahead of its time. It was dark and explosive in many ways. It also had several bold scenes and nudity. Kareena politely refused the film and it was put on the back burner."
The makers however have rubbished these rumours and released a statement.
Balaji Spokesperson said, `Mental Hai Kya is a completely different script, which was written only last year. Balaji heard the script just six months back, and green lit the project. Kangana Ranaut was always the first and only choice for the film, and we are happy that she said yes to it soon after hearing the first narration. Kangana and Rajkummar Rao have been our first choices for the role. The looks that we released last week have garnered fabulous reactions from the audiences and we're so excited to start shoot for this mental ride!`
