I found this speech by Rajni in You Tube. You can see how restless he looks. Whenever he speaks he always tries to capture the microphone, there is lot of restlessness. Make sure you notice his face when he repeats Amitabh Bachchan's name. Later when he says "Indha Rajnikanth endha moolainga?". There is a sense of conviction that I feel whenever I hear him speak.
