Here’s a trailer for High School Musical 3- Senior Year, coming to the U.S. October 24th. The cast has been completely brainwashed into thinking HSM is gonna unite the world better than Coca Cola or Barack Obama! Basically- Zac Efron, Vanessa Hudgins, Ashley Tisdale and the gang do a lot of singing and dancing, but this time it’s on the big screen. We Are The World!
