High School Musical 3: Senior Year, the long-awaited big-screen version of the hit Disney Channel show, isn’t due in theaters until Oct. 24, but we’ve got a first photo from the set to get you through the summer.

Here, Gabriella (Vanessa Hudgens) and Troy (Zac Efron) celebrate the best night of their lives – prom! – as only East High’s Wildcats can: with a magical musical-dance number. “Vanessa’s definitely the stronger dancer,” Efron, 20, tells PEOPLE. “If I forget the next move, she’ll lead me. We have to help each other, that’s what we do.”

“We’re very focused [as dance partners],” Hudgens, 19, adds. “We want to get it right and we have so much fun together that even if things do get difficult, we still try to churn it out and have fun with it.”

Even though the original cast is unlikely to return for a fourth installment of HSM, Hudgens says she and real-life boyfriend Efron may work together again someday. “No one says it’s the last time,” she says. “Who knows what the future will bring.”
