Aasai (Tamil: ஆசை) is a Tamil film starring Ajith Kumar and Suvalakshmi. It was an immense hit and launched the careers of Ajith and Suvalakshmi. It won the Filmfare Best Movie Award South in the year of its release.

The story goes around Suvalakshmi, who is one of the two daughters of an orthodox family. The elder sister being married to Prakash Raj, who plays the role of a military officer, dies due to "heart attack", precipitated by Prakash Raj himself!! Ajith, who dons the role of a charming juvenile falls in love with Suvalakshmi. Prakash Raj tricks the family into believing that Ajith is a drunkard and cheat (in a series of events), which results into a break-up between Ajith and Suvalakshmi. Later Ajith is put behind bars for smuggling, where Prakash Raj narrates the whole story to Ajith. Prakash Raj had killed his wife owing to his lust on Suvalakshmi. After overhearing the conversation accidentally, she flees home to tell it to her father. The movie ends with the death of Prakash Raj, who is caught up in the room with his father-in-law. The prowess of the villainous actor, who with no extravagant action sequences had shown one of the best performances in negative role, on-screen was evident.

Vasanth carefully wrapped the essentials of a commercial cinema around a carefully knit story that had loads of opportunities for all participants.

Produced by Mani Rathnam, this low-budget film grossed Rs.50 million at the box office playing for 210 days successfully. Thus it became the first blockbuster in Ajith's illustrious career who was quickly labelled as Aasai Nayagan by the tabloid. Ajith's salary was just under Rs.50,000. This was the debutant film for Suvaluxmi in Tamil, and she won the audiences hearts by her beauty and stunning performance.
