Now that Miley Cyrus has become a solidified box office success, the execs at Disney can move on to Phase #15 of Montana World Domination.

Months after announcing a big-screen version of High School Musical, the Mouse bigwigs have decided to adapt another one of their shows.  Starting this April, production on a Hannah Montana movie (not a concert tour) will begin.  (Musical starts its filming in March.)

While casting for the pic has not yet been announced, Miley’s father will also be along for the ride.  (How Billy Ray went from Mulholland Drive to this, I don’t know.) 

Based on what is being reported, we should be expecting cameos galore.  Can we say Spice World?
