I'm glad that their releasing character trailers for this movie, I was afraid that all X-Men:First Class trailers will center only on Magneto and Professor X. But YEY! 20th Century Fox gave us glimpses of other characters and we'll start with HAVOK.
Alexander "Alex" Summers. He is well known as Havok, the brother of Scott "Cyclops" Summers. He generates powerful plasma blasts that he has had difficulty in controlling. In the movie, that is the reason why he will be trained by Professor X. The hot and handsome Lucas Till(Hannah Montana the Movie) will play Havok. Witness the beginning on June 3rd.
