It seems that Peter Jackson was kind of loose with the truth.
SIR PETER JACKSON, OCT 1So he lied to the public and when a spontaneous march of worried film technicians occurred in Wellington 3 days after the Oct 18 email, he said nothing other than more union bashing.
The Hobbit is being punished with a boycott which is endangering thousands of New Zealand jobs and hundreds of millions of dollars of foreign income, for no good reason.
SIR PETER JACKSON, OCT 18
There is no connection between the blacklist (and it's eventual retraction), and the choice of production base for The Hobbit. What Warners requires for The Hobbit is the certainty of a stable employment environment.
Interestingly the email was obtained under the Freedom of Information act. The release was later than is proscribed by the rules in these matters and coincides with the Prime Minister and the Minister involved (Gerry "the Despoiler" Brownlee) being on holiday and unable to be contacted.
This story will disappear without trace and the everedge New Zilder will still blame the Film Actors Union.
