Amazon are featuring The Alien Anthology as their Gold Box deal of the day. This makes the US version of the set just $25.00, and that, I believe, is a record. In the UK, the same set is going for £19.89.
In both cases, this is the full six disc version with all supplements included. Both boxes – UK and US – are Region Free too so if you want to import, for whatever reason, you can do that.
I once spent five days writing about this box set. Count 'em:
As long as I don't have to repeat all of day three again we'll be alright. All in all, though, this is the best Blu-ray box set on the market.
