East High insiders we've been in contact with have told us that filming has indeed NOT started yet.
At least not at East High.
For those of you not in the know, filming for High School Musical 3: Senior Year was to begin yesterday, April 21. Filming was then postponed to tomorrow, April 23, and then to May 3 - or so some claim.
Filming could very well have begun on other locations and the crew could be waiting until a more convenient time to move to East High, but that seems unlikely.
There is no word on whether the October 24 release date for the film is still in tact or if it, too has been postponed.
