Eric: 
Playing Dumbledore in the beginning,
but moving on to play Vernon Dursley,
Eric is now in command of a young Ron 
              Weasley
     
Alice: 
    She started out playing 
McGonagall, but changed her mind,
played Mrs. Dursley for a while,
     and is now Hermione
       
Harry: 
   Came in a little later,
 and threw the GM a curve by
 requesting to play a toddler.
  He's still playing Harry.
