The Australian BD is the one to be avoided, not the winner. The film was originally made in widescreen for worldwide theatrical exhibition, but ultimately distribution was only secured outside of the US. The Oz BD has an incorrect open matte transfer, while the others, at 1.78:1, are close to its intended 1.75:1. The Oz disc is a port of the unlisted UK ITV BD.
The German BD is also available on its own (ASIN B00A8C8FG6). It's also been released on legit BD by Divisa in Spain (ASIN B01LZ7ZK4G), in addition to their Resen bootleg.
