No Smoking (2007)
No Smoking is a neo-noir psychological thriller film directed by Anurag Kashyap.The story revolves around a man known as 'K',a narcissistic chain smoker who attempts to kick his habit by visiting a "rehabilitation" center run by a Godman, who employs unconventional,harsh methods to cure his addiction.
A gripping and well-crafted plot, intriguing symbolism and a surreal setting set this film apart. The movie was well ahead of its time, and performed miserably at the box office, but has attained cult status. It is one of those
Nolan-esque movies which force you to think, and has multiple interpretations.
