Moments ago I received this email from Matthew Dravitzki, who is Peter Jackson's spokesperson:
The advertisement is official and came from our production. A preliminary casting call means: We don't have a green light, but we do need to be prepared in the event that we get one! That means having a little look around Wellington for scale doubles as advertised. This is NOT an extras casting call and anyone who doesn't meet the advertised height requirements will be turned away.It certainly answered mine!
When cast, actors playing Hobbits and Dwarves will be normal adult size. The characters in the books are sized differently, as you know. Scale doubles appear in some wide/reverse shots in place of our actors, and with other adult actors when we need people to look smaller - or taller. A visit to the behind the scenes content on the LOTR movies might jog your memory.
I don't have any news for you on greenlight, director or cast. There's no update from LA at this time.
The NZ Dance and Drama Centre is simply being used as a venue for this casting call, and is not the home of our casting department.
I hope this answers your questions.
