Naman Ramachandran After his directorial debut “Rocketry: The Nambi Effect,” which bowed at the Cannes market earlier this year that he also wrote and co-produced, R. Madhavan is back solely as an actor with thriller “Dhokha – Round D Corner,” directed by Kookie Gulati (“The Big Bull”). After stints in music videos, Khushalii Kumar makes her film debut, playing a woman with a personality disorder who is taken hostage by a terrorist. She is married to Madhavan’s character. “It’s very tightly knit and any sort of revelation might give you a hint and ruin it for people,” Madhavan told Variety about the plot of the film. “It looks like a pretty straightforward story, but as the film progresses, nobody is actually who they seem.”
