Kangana Ranaut is going all out for her next, Jayalalithaa biopic. The actress has been preparing for the role by training in the Indian classical dance form Bharatanatyam. It’s been a week now that she has been attending Bharatanatyam classes, all for a grand song, which will be shot with over 100 background dancers. The number will be choreographed by Gayathri Raghuram, a renowned choreographer from the Southern film industry. The performance will have a retro vibe. Directed by AL Vijay, the film is titled ‘Jaya’ in Hindi and ‘Thalaivi’ in Tamil. Before this biopic, Kangana will be seen in Ashwiny Iyer Tiwari-directed ‘Panga’.
