While King Khan did Don, down here in Kollywood, Ajith did the Tamil version of the film. And, while the ongoing Hindi flick Don 2 is a sequel to the star’s previous Don, the ongoing Ajith-starrer Billa 2 is a prequel to his superhit Billa. The first installment of the franchise hit Kollywood in 2007 and gave Ajith a big break. His sleek and stylish portrayal of the dreaded don, Billa, earned him a lot of appreciation and is perhaps one of the reasons that he’s now doing a prequel to the same subject. While the 2007 flick was directed by Vishnuvardhan, Billa 2 is being helmed by Chakri Toleti.
