Suriya was on a diet of cucumbers and egg whites for one whole month to reduce his weight for the young character role.
This film was director Sudha Kongara's dream project ever since the director read an article on Capt.Gopinath in 2011, but went on to make the super hit Irudhi Sutru before starting work on this film.
The film was shot in over 60 different locations including the Hakimpet Air Force station, making it the first Tamil language film to be shot inside the premises.
Given the film's aviation theme, the official site provided users with virtual boarding passes to the trailer launch on YouTube once they entered their names and email IDs.
Aparna Balamurali learnt the Madurai Tamil dialect and dubbed for her character in the film.
