Zac Efron keen on "High School Musical" reunion

Zac Efron wouldn't mind reliving his East High School glory days.

The "That Awkward Moment" actor recently said he that would be "100 percent" interested in joining the cast of a potential "High School Musical" reunion film.

While promoting his new raunchy comedy "Neighbors" on Sunday at this year's South by Southwest Festival in Austin, Texas, the 26-year-old actor told E! News that he and his "HSM" co-stars have mulled over the idea.

"We're all thinking about it," Efron said.

"I continue to see all the guys from 'High School,'" he added. "Every time we do...there's just this look between us. It's so cool because we never forget a single moment of that experience."

A reunion film could mean big bucks for the franchise's studio, Disney.

The first "HSM" film premiered on the Disney Channel in 2006, almost instantly becoming the network's most successful made-for-TV movie of all time. The film's soundtrack became the highest-selling album of 2006.

A made-for-TV sequel was released in 2007, followed by a 2008 theatrical film release, "High School Musical 3: Senior Year," which took in a worldwide gross of $252.9 million against an $11-million budget.

Efron, who was propelled to fame by the franchise, portrayed basketball star Troy Bolton, who finds himself in a Romeo-and-Juliet type romance with transfer student Gabriella Montez, played by Vanessa Hudgens.
