But not any more. Disney has just confirmed that High School Musical 3 – the final movie in the High School Musical trilogy – will be a full feature release that people will have to save up their pocket money and pay to see in cinemas.
Needless to say, the news has excited young High School Musical fans and creepy middle-aged perverts who've just worked out that they'll be able to see the outline of Vanessa Hudgens' boobs on a gigantic screen alike.
High School Musical has, by all accounts, been a sensation for Disney. It spent all that money painstakingly animating crap like Treasure Planet and Home On The Range and all it really needed to do was find a bunch of kids that looked as if they'd been made in a sinister injection-moulding factory and get them to sing songs about how everyone is special on the inside on a TV movie to make the cash come rolling in.
Now people put on their own High School Musical plays, listen to High School Musical CDs, play with High School Musical action figures and try to look like High School Musical star Zac Efron by varnishing their faces, wearing plastic wigs and pouting into a mirror for days at a time. We expect.
But soon it'll be time to say goodbye to High School Musical so that its young stars can move on with their lives and make that softcore pornography DVD they've been teasing us with for so long. And, because the old 'everyone in High School Musical is so stupid that they'll have to repeat classes until they're 40' ruse won't work, the upcoming High School Musical 3 will be the series' final outing.
But what an outing it'll be, because High School Musical 3 will be the first to get a full theatrical release. People reports:
All six of the High School Musical stars have officially signed on for High School Musical 3: Senior Year, Walt Disney Studios Motion Picture Productions announced Monday. Zac Efron, Vanessa Hudgens, Ashley Tisdale, Corbin Bleu, Monique Coleman and Lucas Grabeel will star in the third and final instalment, a feature film. Director Kenny Ortega tells PEOPLE he's excited about working one last time with the cast… "I am the luckiest guy in the world and I know it," Ortega says. "This will be our last time together and I love working with these kids so much. It's going to be great."
But what about the plot of High School Musical 3? Somewhat predictably, it will centre on Zac Efron and Vanessa Hudgens coming to terms with the fact that they'll soon have to leave school for different colleges – which we presume to be the Academy For Dim-Looking Ladyboys and Naked Slut Central respectively – and deciding that the only way to get over their heartache is to sing plenty of family-friendly songs about how everyone is special on the inside at each other.
And then it'll be over, unless of course High School Musical takes the Saved By The Bell route and makes a High School Musical: The College Years film and a High School Musical: The New Class film where one of the original stars has inexplicably become a teaching assistant during the day and a disgusting internet sex tape star at night.
Which, you know, wouldn't be too much of a leap.
