Kalaiyarasan, reportedly, plays the role of an army man in Airaa and will be sharing a considerable amount of screen space with Nayanthara. "I am an army veteran in his late thirties, who is calm-headed and has a mature understanding of the situations around him. Most of my scenes will be with Nayanthara’s character Bhavani," the actor had told The Hindu in an interview.
Apart from Nayanthara and Kalaiyarasan, Airaa also features Yogi Babu, Jayaprakash, Meera Krishnan, Master Ashwanth and Kalaipulli Leela among others in significant roles. The movie has been produced by Kotapadi J Rajesh with music by Sundaramurthy K.S.

Airaa is a full-on Nayanthara show with a great idea, not-so-great execution. The film, of course, has an interesting premise, which ‘Lady Superstar’ nails it, both in terms of style and performance.

"Nayanthara plays a dual role in Airaa for the first time. There are no connections between two different characters. Airaa is going to be a different experience," director KM Sarjun earlier said at the film's press meet in Chennai.
"Every day people ask me why I didn't do a film like Madras. Sarjun and I were supposed to work on Echarikkai Idhu Manidhargal Nadamadum Idam. Airaa will be an important film in my career. Besides horror angle, there is an emotional angle in the film," said actor Kalaiyarasan at the press meet of the film.

"#Airaa [3/5] : Horror and Comedy 1st Half.. Emotional 2nd Half. Not the usual flashback. The Butterfly effect comes into play. Lady Superstar #Nayanthara is fab in both the roles, especially the dark skinned gal role. @KalaiActor is good. Music Dir @SundaramurthyKS 's BGM is a big plus.
