The scene where Annaamalai enters a ladies' hostel and gets terrified by a snake was shot at Chakra House, Alwarpet. A snake was brought specifically for the scene. The owner of the snake earlier worked in previous films of Rajinikanth. Krissna told cinematographer P. S. Prakash to use zoom lens so that he could adjust the camera according to the situation. After the scene was finished, the members of the crew enjoyed the shot. Krissna congratulated Rajinikanth and asked him how he performed it so well and if it was planned, and Rajinikanth replied it was not planned; expressions in the scene were a result of his fear. In the same scene, Shanmugasundaram came with initial dialogues to convey Annaamalai's fear. Krissna felt that dialogues were redundant in such situation. Rajinikanth insisted to keep "Kadavule Kadavule" (Oh God! Oh God!) as the dialogue. Krissna agreed as it went well into the situation of the scene. According to Krissna, nobody on set realised that the snake's mouth was not stitched; it was only after filming ended for that day that the director came to realise that Rajinikanth's life was at risk the entire time.
