Who will play roles of Gemini, ANR and NTR in Savitri bio?

Priyanka Dutt, daughter of Ashwini Dutt is producing the bi-lingual film on legendary actress Savitri. The film is being directed by Nag Ashwin who tasted success with Evade Subramaniyam which was produced by Priyanka Dutt. Savitri made an strong impact among South Indian people with her spectacular performance. Every next generation heroine treated Savitri as her role model in both Tollywood and Kollywood. Obviously every one interested who plays the role of Savitri?

Nag Ashwin was selected Keerthi Suresh for the role of Savitri in Mahanati. It's interesting how Keerthi will do justice to her role. As per buzz, Keerthi is doing home work by watching Savitri classics to study her mannerisms etc. Reportedly, Samantha will take up role of Jamuna (Contemporary Heroine of Savitri). Whenever we discussed about Savitri career in films some male actors always remembered like Gemini Ganeshan, ANR and NTR.

Gemini Ganeshan aka (Tragedy King in Tamil) with Savitri did many films in Tamil. NTR replaced Gemini in all remake films in Telugu. What NTR's role in Missamma was played by Gemini both in Hindi and Tamil. Savitri and Gemini chemistry mesmerized Tamil Audience. Savitri did films with ANR like Devadas, Donga Ramudu and Mugamanusulu. All these were classics. Pairing with NTR turned Savitri career to peaks. Pandava Vanavasam, Gundamma Katha, Devatha and Missamma were few among them. Rakthasambandham was reached highest in brother-sister sentiment. NTR and Savitri did justice to their roles as brother and sister in the movie. Keeping in view the above, it's very tough to the director in selecting roles for Gemini, ANR and NTR for Mahanati film.
