Gone are the days when permission to film in railway stations and airports was as easy as pie. Due to these crowded places becoming soft targets for terrorists, the authorities are leaving no stone unturned with their security measures. Therefore, obtaining permission to shoot in railway stations and airports has become very hard and troublesome. Even when permissions are granted, filmmakers find it extremely difficult to complete all the shots within the stipulated time.

The makers of the film 'Sathyam' needed an airport to film an action sequence. Airports in India said NO while an airport in Dubai said YES. The crew went over there and canned the shots.

Jeevan was supposed to star in a film titled 'Payannigal Gavanathirkku' and the film was to be shot extensively in railway stations. Since permission did not come their way the film sadly had to be abandoned.

Dhanush's 'Padikkadhavan' needs a railway station to can some 'vital' scenes. Not sure if permission would come their way, the filmmakers decided to erect a railway station set at the Ramoji Rao Film City in Hyderabad. Sources say tremendous effort has been put in to bring about the authentic effort.
A wise decision indeed by the team that bears the name 'Padikkadhavan'.
