Alex Pettyfer as Jace
Alex is well know from Magic Mike, Wild Child and I am Number Four. He's the perfect character, he can play cocky really easily and he he's blonde and has the right look.
Emma Stone as Clary
She's funny, has good dry humor and like Alex has the right look for the part.
Phoebe Tonkin as Isabelle
I love Pheobe and as shown from the Secret Circle she can be arrogant and kick some ass. But as much as I want her on the TMI show I don't because I don't want her leaving The Originals. Ever.
I haven't decided anyone who is really right for Alec and Magnus
Drew Roy as Jordan Kyle
Jessica Parker Kennedy as Maia
Jodi Lyn O'Keefe as Maryse
Julianne Moore as Jocelyn
Charilze Theron as Camille
Logan Lerman as Simon
Yeah, that's my dream cast, feel free to tell me yours :)
