This is an amazing High School musical version of Star Wars: A New Hope. It is pretty amazing. Darth Vader is a bit weak but Leia is amazing and the rest of the main cast are quite impressive. The score comes from various musicals, Les Miserable, Grease, Miss Saigon among many others. This is definitely worth watching.
