On the 57th birthday of Chiyaan Vikram, the video of the making of his new film 'Thangalan' was released. Along with this, the makers also shared the poster. It is very difficult to recognize Vikram in this BTS (Behind The Scene) video. The way Vikram has transformed himself for the role of 'Thangalan' is astonishing. Talking about the film, it is based on the real events that happened in 'KGF' i.e. Kolar Gold Fields. The story focuses on the people who worked in 'KGF' during the British rule. According to reports, director Pa Ranjith worked on the script for four years before starting the film. He prepared the story keeping Vikram in mind. Since then, Vikram started growing beard to become 'Thanglan' and working on his body accordingly. Many actors including Malvika Mohanan, Parvathy Menon, Hari Krishnan will be seen in it.
