Tollywood superstar Nagarjuna's son Naga Chaitanya, who was seen in a cameo in Gautham Menon's Vinnaithaandi Varuvaayaa as himself, is all set to debut in Tamil as a hero. He will appear in a full-fledged lead role in director Radhamohan's next project, touted to be a Tamil-Telugu bilingual. According to sources, Naga Chaitanya will play the lead role in both versions. When contacted, Radhamohan declined to reveal details about the project, but confirmed that talks are on with Naga Chaitanya. "It's true that I'm in talks with Naga Chaitanya for my film, but details haven't been finalized. I'm still deciding on the cast of the film. It's too early to talk about the project," he said.
