It's not long before they are discovered by a another group of the menacing blind people who omimously feel their way around the outside of the pub whilst Bill and Jo sit tight inside
This is much like in Shaun of the Dead when Shaun goes to rescue his girlfriend Liz and they too barricade themselves in their local, The Winchester. Soon the zombies return and circle the pub.
The images here really struck me with their similarity
There were also some fantastic images in Day of the Triffids of London 6 years after mass blindness and a mystery virus had caused depopulation. I have an unwatched copy of 28 Days Later that I shall view with a new interest.
