Mark you calendars because there are only five months to go until High School Musical 3 hits theaters this October. But for those of you with kiddies who can't contain themselves that long (or perhaps it's you who's the HSM groupie), this morning GMA went behind the scenes of the third installment of the crazy-popular franchise and even caught up with some of the cast members, including Vanessa Hudgens and Zac Efron (sporting his finest prom wear). - Gina DiNunno

Are you pumped to see part three of the Disney sensation? Think it will be as good as the first two? Think Zac looks exceptionally spiffy in his suit and boutonnière?
