the assignment. He was disappointed when Shankar recruited Manikandan for the project. However, when Manikandan abandoned the project after completing almost half the film, Shankar asked Varman to shoot the remaining portions of the film. Varman had committed to work in Bengali director Buddhadeb Dasgupta's next film, work on which was scheduled to begin shortly; he dropped out of it to accept Shankar's offer and termed working in Anniyan "a dream come true". The film credits both Manikandan and Ravi Varman as cinematographers in title credits. Preparation and character looks Vikram allotted 18 months and 190 days of his call sheet for the film, including 165 days of bulk dates spread across six months. Speaking on the extent of his involvement in the filmmaking process, Vikram said, "Before beginning the film, I was totally involved in the research and preparation, but once on the sets, I go by what the director says." He further clarified that he discussed every shot with Shankar, went for re-takes where necessary to make the scenes better, and gave suggestions, but left the "ultimate verdict" to the director. Disclosing that, among the three shades to his character, he found playing Ambi to be the toughest, he reasoned, "Because as a hero you are not used to being a wimp on screen. It's difficult digesting getting beaten up." In contrast, being a graduate in English literature, he found playing Remo much easier and more in his comfort zone. In an interview with Gulf News, Vikram spoke of the challenges in portraying all three characters while wearing the same costumes. He said, "I love such challenges. [...] Although the costume defined each of the three characters in Anniyan, there were scenes where Ambi would suddenly become Remo and Remo would become Anniyan. There I made it dramatic to bring out each character." He credited his wife Shailaja Balakrishnan, a psychologist, for helping him in fleshing out the character of Ambi, a person who has multiple personality disorder. In a conversation with film critic Baradwaj Rangan, Shailaja recalled the times the film was being made and spoke of Vikram, saying, "I felt we should live in two houses. It's not easy to live with a man who can get that eccentric, an actor who wants to be that difficult on himself. I wouldn't say he becomes the character, but there's definitely some kind of internalisation." Vikram confessed that
