KEY POINTS:
The filming on High School Musical 3 hasn't even been completed yet, but Disney has confirmed they are already working on a High School Musical 4.
Disney Channel Worldwide chief Rich Ross told Hollywood Reporter yesterday the Mouse House is planning to make the fourth instalment of the
teen mega-hit a made-for-tv movie, although that could change.
"We are writing 'High School Musical 4,' " Ross said.
"Are we going to have all the cast back? Probably not. Will we have some of them? I hope so."
The six original cast members are currently filming High School Musical 3: Senior Year, the first of the series to open on the big screen. HSM3 is due in theatres in October this year.
