In it, the irrepressible diva Sharpay Evans, recent graduate of East High School, seizes the spotlight in this movie written by Robert Horn.

Ashley Tisdale will reprise the role she made so popular in the High School Musical TV movies and feature film. Tisdale executively produces the movie alongside Barry Rosenbush and Bill Borden (both of the High School Musical movies).

Aspiring thespian Sharpay Evans, who was once a big, fabulous fish in a small pond (a man-made pond at a resort country club that her father owns), is finally about to meet her destiny on Broadway, and luckily, theatre lighting highlights her hair and skin tone beautifully. Her big break comes after a talent scout spots her performing with her dog Boi at a charity gala, and now there’s not a marquee big enough or lights bright enough to contain the glorious fame she plans on having. Sharpay and Boi head to New York, but theatre is a dog-eat-dog world, and nothing turns out as Sharpay expects, especially when she meets her match in a rather daunting Broadway starlet (who arrived in Midtown Manhattan as a recent winner of So You Think You’re America’s Most Talented Performing Idol).

The Great White Way is all Sharpay's ever dreamed of, especially since she already has everything else. Life in the big city is a shock, but there's an even bigger bombshell when Sharpay finally realises the Broadway role is really for Boi, not her. Putting her disappointment aside, she sets out to make Boi the most fabulous canine star to hit the stage, with the hope that his fame will become her fame (after all, she is his entourage and she holds the leash). Before long, Sharpay makes a new friend in a student filmmaker, Callem, who finds her to be a fascinating subject. Meanwhile, Boi finds puppy love on a Big Apple adventure of his own.

Tisdale originated the role of scene-stealing drama queen Sharpay Evans in High School Musical, followed by its sequel and feature film. A fan favorite, she won an MTV Movie Award for her portrayal. Her other credits include The Suite Life of Zack & Cody, the voice of Candice in Phineas and Ferb and the feature film Aliens in the Attic.

The Emmy Award-winning High School Musical has reached more than 290-million viewers, in 24 languages. Its sequel, High School Musical 2, has been seen by nearly 300-million total viewers in over 27 languages. Walt Disney Pictures debuted High School Musical 3: Senior Year in 2008. It grossed more than $250 million at the worldwide box office.
