National Award-winning actress Kangana Ranaut's Thalaivii, a biopic on former Tamil Nadu Chief Minister J. Jayalalithaa, is scheduled for a worldwide theatrical release on September 10. Directed by blockbuster director A. L. Vijay and produced by Vishnu Vardhan Induri and Shaailesh R Singh, the upcoming film made as a Tamil-Hindi bilingual and dubbed in several languages, also stars Arvind Swami, who is portraying legendary actor and late Tamil Nadu Chief Minister MG Ramachandran, popularly known among the masses as MGR. With promotions already underway for Thalaivii in light of its release next month, the makers on Friday released a short promo teaser for the 'Unthan Kangalil Ennadiyo' song featuring Kangana Ranaut and Arvind Swami. 

Composed by G. V. Prakash Kumar and lyrics penned by Madhan Karky, the 'Unthan Kangalil Ennadiyo' song in Thalaivii will be released in full on August 30, with the first visuals in the promo teaser taking us back to the golden days of Tamil cinema and giving us a glimpse of the on-screen romance between MGR and Jayalalithaa. Thalaivii has been carrying tremendous hype right from the moment the film was announced and is expected to take a solid start in theatres around the country considering it is a pan-Indian venture produced jointly under the Vibri Motion Pictures, Karma Media And Entertainment and Zee Studios banners in association with Gothic Entertainment and Sprint Films. 

Thalaivii has already seen a delay in its release twice, with Kangana Ranaut making it clear that the film will be coming out only in theatres after rumours sprung up stating that it might head for a direct OTT premiere. Apart from Kangana and Arvind Swami, the film's star cast also includes Prakash Raj, Jisshu Sengupta, Poorna, Madhoo, Bhagyashree in pivotal roles, while legendary writer KV Vijayendra Prasad has penned the screenplay. Thalaivii's story will revolve around the life journey of Jayalalithaa from cinema to her entry in politics, while also showing glimpses at iconic leaders like MGR and other major political names in Tamil Nadu.
