Tamil director Kasthuri Raja reacted to actress Nayanthara's open letter to his son, actor Dhanush, saying, "There's no time to answer those who chase us." Speaking to TOI's Samayam, Kasthuri said, "Like me, my son is focused only on work." Nayanthara's claim of waiting for two years for Dhanush's approval for using 'Naanum Rowdy Dhaan' visuals is false, he added.
