Hey, I just saw that SPACE:1999 is getting a super-deluxe release in Australia from IMPRINT FILMS. Looks like it has all of the extras of the UK and US SPACE:1999 Blu-rays. So I did some looking, and I see one of the same names behind this new company that used to be behind the TV division at MadMan, who produced that UFO DVD set that had more extras than any other release.
So here's hoping for a Australian UFO Blu-ray release!
