Sivakarthikeyan was last seen in director PS Mithran's Hero which was released in theatres in 2019. The actor hasn't had a release in 2020 due to the novel coronavirus pandemic. He is thrilled about the release of his upcoming film Doctor, directed by Nelson Dilipkumar. The film will release in theatres on October 9.
Ahead of the film's release, Sivakarthikeyan met the media and spoke about the film. He said, "I am glad to meet you all after a couple of years. When it comes to penning lyrics, I was so unsure about it. It was director Nelson, who motivated me to do it with his debut movie ‘Kolamaavu Kokila’. Writing lyrics for Chellamma was easy, but ‘Oh Baby’ was quite tough and challenging. I had to gain good reception for it indeed, and I am glad that people are enjoying and appreciating the song. I have very few dialogues in this movie, say around 10. Its other characters keep talking a lot and it was really difficult for me to keep silent. I was wondering how Nelson could think of such a characterization for me. But to see the final product, I am glad that it has come out well. I thought I am a tall actor until I met Vinay. I had to use the apple box while sharing the screen space with him to match the height. His screen presence and voice are going to be a pillar for this movie. Priyanka’s Tamil knowledge was really helpful. It is always easy to work with heroines with Tamil knowledge as we can be pretty sure about the end product while shooting itself. Redin, Yogi Babu has done a fabulous job in this movie. Arun bro’s dedication to this movie will be appreciated for years to come. I miss him a lot. Vijay Karthik’s cinematography is awesome and the audience will say the same while watching the movie in theatres. Anirudh has been the ID Card for this movie from the time of the announcement of this project. The movie will be a milestone for everyone in the cast and crew."
