Apple is offering a full-length movie for download from the US iTunes Music Store.

High School Musical is a made-for-TV Disney movie. The video runs for 1 hour 39 minutes and weighs in at 487MB.

It costs the standard $1.99 that all video content costs on the store.

There is some speculation that Apple is testing the water before launching a fully fledged movie download service.

Macworld will confirm download times shortly.
