I think someone mentioned this previously. There is a new Harrison. I just checked the cast on IMDB. The old Harrison is credited to twin brothers, Luke & Evan Kruntchev. The 2013 Harrison is credited as Jadon Wells. I swear the old Harrisons seemed mentally challenged. They couldn't deliver a line. I think they must have told them to not say anything and just act dumb. Of course it is very difficult to cast an infant and hope they can act in 3 or 5 years.
