Doctor is Sivakarthikeyan's upcoming film directed by Nelson Dhilipkumar and bankrolled jointly by Sivakarthikeyan Productions and KJR Studios. This movie stars Priyanka Arul Mohan of Gang Leader fame as the heroine. The young girl Deshna, who had acted in a minor role in Sivakarthikeyan's latest release Hero, seems to be a part of Doctor also. Sivakarthikeyan has been going through an eventful time in his career with his recent releases see-sawing at the Box Office. Sivakarthikeyan would be pinning all his hopes on Doctor and Ayalaan. He would resume shooting for both these projects once lockdown is over. Ayalaan, bankrolled by RD Raja's 24AM Studios, has just a few days of shooting left to be canned but the film still has plenty of post-production work left. This movie will see Sivakarthikeyan pairing up with Rakul Preet Singh and will have music by the Mozart of Madras - AR Rahman. Isha Koppikar, Shard Kelkar, Yogi Babu, Karunakaran and Bhanupriya are all a part of this movie's cast. Nirav Shah is handling the cinematography and Ruben is taking care of the editing duties of Ayalaan.
