Miley Cyrus at 'Hannah Montana and Miley Cyrus: Best Of Both Worlds Concert 3D' film premiere at El Capitan Theatre. Hollywood, California - 17.01.08

Following the success of the High School Musical movies, Disney wants Cyrus to conquer cinemas, after becoming a TV hit and selling out an entire live concert tour.

Sources tell Star magazine writers are working on the script, and Disney bosses hope to star shooting later this year (08).

An insider tells the tabloid, "The movie is set to begin filming this summer and the script, which needs a little tweaking, has been greenlighted for the past few months."
