As far as I can tell, this one was originally meant to be a four hours television miniseries, but things didn't go as planned. It sold better abroad and first aired e.g. on AXN in South Korea and M6 in France.

It was first (and until now only) released digitally in the US as a 2x90min miniseries:

In the UK, it has a 2017 digital and physical release.

Which is why I used 2014-07-07 as the release date and left the network field blank.
