Time Magazine has chosen Zac Efron to join the 100 most influential stars list. Other people include Barrack Obama, Opera Winfrey, and a whole lot more. Clarie Danes writes about Zac, "I suppose we all know that Zac, 21, is a song-and-dance man. What is less known -- and what I had the privilege of learning firsthand -- is that he is a performer of great subtlety and vulnerability... It seems Zac is not only an entertainer but also an artist. He is going to make us swoon for many years to come."
