Miley Shedding her ears?

Miley Cyrus has been under the Disney umbrella for as long as her short career has spanned. Now, the tween queen has announced that she'll shed the Disney ears for a more serious project (or at least that's what she's calling it, anyways).
Cyrus will work with best selling author Nicholas Sparks to create, simultaneously, a new book/movie. Cyrus will play the lead, and her mom Trish will serve as an executive producer. Does this ring a bell for anyone else? Can you say Hilary Duff and her mom Susan? Hilary starred in "A Cinderella Story", mom Susan served as the movie's executive producer. Funny. Hilary also got her start on the Disney Channel. Hum, really funny. Both starlets used the expanded fan base they acquired with successful music sales to boost their transition to the big screen (Hilary Duff went multi-platinum with "Metamorphosis" while Miley has hit gold with "Breakout".) I'm getting deja vu here.
The question is whether or not Miley's star power will translate into success of the big screen. Will her tween audiences follow her? Will the content of the film be enough to engage her older fans too? Only time will tell, but I'm guessing that much like Hilary Duff's Lizzie McGuire stigma, Miley will have Hannah Montana on her back for quite some time.
