Southern actor Siddharth Suryanarayan, known for Tamil films such as "Boys", "Aayutha Ezhuthu" and "Udhayam", says his upcoming Tamil-Telugu bilingual period-romance "Kaaviya Thalaivan" will be the toughest project in his career.
"Getting into pre-production tomorrow for my most difficult film yet. Vasanthabalan's 'Kaaviya Thalaivan'. It's going to be a special journey," Siddharth posted on his Twitter page.
Vasanthabalan, known for National award-winning Tamil drama "Veyil", will helm the project, which is said to be based on the relationship between renowned southern singing couple S.G. Kittappa and K.B. Sundarambal.
The team is yet to zero in on the rest of the cast, including the female lead.
Sashikanth, who had previously produced Siddharth in Tamil-Telugu bilingual "Love Failure", will produce this film under his home banner YNOT Studios.
Meanwhile, Siddharth is awaiting the release of his Tamil comedy "Theeya Vela Seiyyanum Kumaru".
