Aishwarya Rai Bachchan was originally intended to play the role of Mahi Arora. The first look of the movie was revealed at the 64th Cannes Film Festival with Bachchan but she was later replaced with Kareena Kapoor.
The release of Mahi's sex tape in the film can be seen to mirror actress Kareena Kapoor's leaked video clip in real life, where she and then beau Shahid Kapoor are seen kissing, this clip also led to much controversy.
The poster is also strikingly similar to a Indian novel 'The Lost Flamingoes of Bombay' by Siddharth Dhanvant Shangvi. Moreover, the book's leading character "Zaira" has been portrayed as a reclusive queen of Bollywood, which again matches the theme of Bhandarkar's film where Kareena plays the role of a glamorous Bollywood superstar "Mahi Arora."
When Kareena is rehearsing with Arjun for a dance, a clear shot of her back, shows that the outfit is backless. However, when the scene shifts to the makeup van, Kareena is wearing the same outfit but a strap has appeared on her back.
Mahi Arora uses an iPhone but whenever she uses it, the screen does not turn off while making a call. The proximity sensor in an iPhone turns off the screen when it's held to the ear.
When Kareena shoots the sex scene the camera is handheld and shaky but when she sees it with Divya Dutta on laptop it looks like as if it's shot with camera held properly
