Rajinikanth said he was "doubtful" about Malayalam actor Fahadh Faasil playing an entertainer in 'Vettaiyan' because he'd seen him do only serious roles. "But [director] TJ Gnanavel was certain," he said. Calling Fahadh "extraordinary", Rajinikanth added, "One won't know where he's, but as soon as you call him for shot, he'll come running and finish his portion in no time."
