You might have thought that High School Musical 3 was to be the swansong of the series, leaving tweens everywhere with three near-identical Grease rip-offs to cling onto.

But that’s not the case at all. Eager to keep churning out enough High School Musicals to keep everyone in solid gold bathtubs for a decade, Disney has announced that there’s a High School Musical 4 in the pipeline.

However, don’t expect too many of your favourite High School Musical characters in High School Musical 4, because rumour has it that there’ll be a mostly-new cast. Which we’re eternally thankful to Disney for – after all, the High School Musical cast of today is the middle-aged pervert’s grubby naked sex fantasy object of tomorrow.
