Atlee's Bigil with Vijay and Lokesh Kanagaraj's Kaithi with Karthi are ready to set the screens on fire this Diwali. And both are releasing on the same day- October 25. It can be called an epic clash because the buzz for both the films have sky-rocketed in the past few days. Kaithi promises action and more action, nothing less and there are no forced comedy, romance or songs. As for Bigil, it will be a typical Vijay-Atlee entertainer which is evident from the hair-rising trailer. Though, Vijay's Bigil might have an upper hand given the star's BO position, Karthi Kaithi too have made the movie buff sit up and take notice. Let us wait for the clash of the titans on October 25 before jumping into conclusions.
