Kollywood star Karthi is all set to start with his next project after Siruthai. Sources say that the actor might take up his next project with either director Boopathy Pandian or Jagan. However Karthi seems to be taking a while assessing the projects before signing it blindly. The actor had said earlier that he will be more choosy in signing projects. Close sources however report that his next project will be with Green House Studios.
