I can understand it from the union's point of view in the case of mostly American movies but it's an international production (large chunks of it utilising UK talent already).

When the last two prequels were most made in Australia the LSO was still used for the tradition of using them.

If Disney follows through with this, what to stop the cold opening (with the crawl) tradition ending? Wasn't it complaints about that sort of thing which caused the rift between Lucas and the DGA and SAG?
