Reports say that Kannan has managed to complete only 25 percent of the film. The movie was announced a year ago and the makers of the film were not happy with the growth of Karikalan. The repeated delay in the shoots for one or the other reason left the movies bosses red faced. Hence, they have replaced him with Gandhi Krishna, who has written the script.
Gandhi Krishna has claimed that he has been approached by the makers of the film but nothing has been confirmed yet. However, the producer of the film have said that they are not replacing Kannan but a few changes are being made in technical departments including cinematographer Karthik, who is being replaced by Rathnavelu.
Karikalan has an inspiring story of one of the popular Tamil kings, Karikalan Chola. Bollywood actress Zarine Khan is enacting the character of Velir girl and Anjali will be seen in an important role.
