I thought I recognized it, but there's another small budget Aussie Apocalypse movie about aliens trying to save us from zombies, and it was the most intentionally and gloriously stupid thing I've ever seen. I wish I remembered the name, all I remember is a gruff Russel Crow knockoff in a long coat and broad hat with sawn off shotguns pulling some Resident Evil level nonsense.
On topic, just got my anxiety meds. Hope this helps... I don't want to stay on this particular wagon for long.
