While Disney is hard at work concocting the next big teen musical, they also are covering the rest of their bases. Variety reports that the Mouse House has signed on "Life Unexpected" star Britt Robertson to take the lead in the TV adaptation of Meg Cabot's "Avalon High."

For those of you who remember that far back, Meg Cabot also penned another little book called "The Princess Diaries," which Disney adapted and boosted Anne Hathaway to international fame. While that was made for the big screen and this for television, there still is a good chance of this Disney Channel film being Britt's big break.

The story follows a teenager named Ellie who transfers to a new high school called Avalon High. She soon discovers that her classmates are reincarnations of King Arthur and his court, for better or for worse, and that she also has a role to play in the unfolding story. The film will also starSelena Gomez's "Wizards of Waverly Place" costar Gregg Sulkin as well as Joey Pollari, Devon Graye and Molly Quinn.

The script was written by Julie Sherman Wolfe and will be directed by "90210" and "One Tree Hill" director Stuart Gillard. "Avalon High" is starting production in New Zealand right now and is expected to hit the Disney Channel in the fall.
