From Jaden

Have you looked at the character descriptions? They are downloadable on the news and casting pages.  That should tell you all you need to know. We are open to casting professionals as well as unknowns. Remember this open casting is for all parts across the film, so even if you read for EVE we might consider you for a supporting role if you are right for the part. The 3 leads must be able to sing and act – dancing can come later.
