This movie is based upon on a short film by the same title, directed by debutant Arun Kumar of Naalaya Iyakunar fame.
The makers had a video campaign 'Why we love Padmini' where owners of this car confess how crazy they are about it. Director Priyadarshan shares in this video that he'd told his son that he will never agree to sell his Padmini.
The pivotal character in this film is played by the vintage car, Padmini. So, the makers had organized a grand road show with two Padmini cars, which made a procession to Chennai from Nagercoil and Coimbatore.
