I sat and listed all my loose DVDs in a spreadsheet last night... partly self-isolation boredom and partly because I am tired of forgetting and mis-remembering which parts of my collection are still left in the UK. SO. That's good and helpful going forward.
I found I do NOT have Day of the Dead here, booo. But I did find it on Tubi, yaaay.
They also have the disappointing "remake" and a fairly impressive selection of other zed movies, should you feel so inclined.
Stay safe, everyone.
