The Disney Channel has tapped Mexican helmer Patricia Riggen (“Under the Same Moon”) to direct its new TV movie musical “Lemonade Mouth,” based on the bestseller by Mark Peter Hughes.

Casting is under way for fresh faces between ages 15 to 17 to take on the roles of five teens who meet while in detention at a Rhode Island high school and form a hit garage band.

“We’ll be conducting a nationwide search for young actors-singers-musicians to fill these roles,” Riggen said.

Exec produced by Debra Martin Chase (“The Princess Diaries,” “The Cheetah Girls”) with a script by April Blair, “Lemonade” will begin shooting mid-July in Albuquerque, N.M. The musical is set to air in summer 2011.

Riggen will next helm “Vivaldi,” about the composer, with Jessica Biel, Luke Evans and Ben Kingsley attached. Biel plays Vivaldi’s forbidden love, soprano Anna Tessiero Giro.

Violin virtuoso David Garrett will limn Vivaldi’s father and also play the violin for the soundtrack and supervise the score. Raffaela de Laurentiis, Ica Souvignier and Michael Souvignier produce.

Fox Searchlight released “Under the Same Moon” in 2008. It became the third highest-grossing Mexican pic of all time in the U.S.

Riggen is in Cannes to present her short “Lindo y querido” (Beautiful and Beloved) in Critics’ Week.
