They are using older actors and characters because if you remember for Harry Potter the first few movies took forever to get out because the actors were so young and there are restrictions on how long they could work each day. By increasing the ages they do 2 things...1) make it more appealing to the older crowd that doesn't read and 2) make it so they can get all the movies done in a more timely fashion.
