The Hunger Games Character Guide
Caesar Flickerman is the Master of Ceremonies and commentator for the Hunger Games, along with Claudius Templesmith. He has served as the Master of Ceremonies since the 50th Hunger Games, but his unchanged appearance leads Katniss to speculate that he had received extensive surgeries to retain his youth.
He also interviews each tribute on live television the night before the Games begin and is known to have an innate ability to relax a tribute's fears to have a casual discussion with him or her. He is also known for wearing a different color of hair and suit for each Hunger Game, including a frightening blood-red color of hair used in the 73rd Hunger Games. In the movies, he is also known for flashing a huge smile.
