Shahid Kapoor and Alia Bhatt starrer "Shaandaar" will throw light on a medical condition -- insomnia. Insomnia is a sleep disorder characterised by difficulty in falling asleep.

Vikas Bahl's "Shaandaar" has a twist that the makers had kept under wraps till now. Shahid and Alia will play the role of two insomniacs.

"Yes, it is true. Shahid and Alia are playing characters who are suffering from insomnia, which is, inability to get sleep. Insomnia is something most people have gone through at some point in their life which makes the film and their characters extremely relatable," said director Vikas Bahl in a statement.

The makers of "Shaandaar" have also included an old song from the 1958 film, "Post Box 999", which goes well with the concept of insomnia.

"Apart from being a destination wedding film, 'Shaandaar' is about this story of two insomniacs. Shahid's and Alia's characters don't get sleep at night, so the makers of the film bought the rights of the popular track from the 1958 film 'Post Box 999', 'Neend Na Mujhko Aaye' (picturised on Sunil Dutt and Shakeela). For 'Shaandaar', the romantic number has been recreated by Mikey McCleary and picturised on Alia and Shahid. The song, originally sung by Hemant Kumar and Lata Mangeshkar fits perfectly in this film about insomniacs," added a spokesperson in the statement.

Along with Shahid and Alia, "Shaandaar" also features Pankaj Kapur and Shahid's sister Sanah Kapoor. The film is slated to be released on 22 October.
