Harmony Korine says his cast for 'Spring Breakers' is ''the ultimate dream''.

Disney stars Vanessa Hudgens and Selena Gomez join 'Pretty Little Liars' actress Ashley Benson and the director's own wife Rachel in a a quartet by-and-large shedding their wholesome images on screen.

Korine told The Guardian newspaper: ''[The cast] was the dream, the ultimate dream for me. As I was writing it I thought, 'If you could have the dream, what would it be?' ''

The crime thriller follows a group of college girls who get caught up with a drug dealer during their spring vacation and the director was delighted with an ensemble of performers who contrast the characters they have taken on.

He added: ''The dream would be these girls and what they represent. There's obviously something very exciting about working with these girls who are, in some ways, in real life, representative of that culture and that pop mythology.

''And also people can identify as personalities that are complete contrasts to what they're portraying in the film.

''I love that that part is a conceptual shock on top of the actual film.''
