I just watched this (again) for the sci-fi challenge. I must have had this thought before, but, whatever... I was just startled, watching it, by how influential it seems to have been. I should have written this as I was watching it, I would probably have remembered more.... I just kept constantly being reminded of more modern films, while watching it, and of course that is probably because those more modern films were partly inspired by, or at least doing homage to, Day of the Triffids.

The dude waking up in the hospital room, the morning after some horrifying pestilence or other events has run its horrifying course through the community, has been done in 28 Days Later, The Walking Dead, and possibly some other movies I have seen. I will come back and write in anything I remember here. Anyway, those movies and TV shows aren't necessarily inspired by DotT, but I just feel like someone on the set of both those sets must have mentioned the similarity to DotT, and maybe stuck in some kind of Easter egg for alert fans.

The scenes at the lighthouse made me think of The Fog, of course. I bet John Carpenter has talked about any connection that might exist here, in some interview... I can't remember hearing this, but I bet he has.

Also, just the way the Triffids move, and what they are like, just in general... it just feels like DotT might have been more of an influence on the zombie apocalypse sub-genre than some of the early films that are actually about zombies.

I will come back and post more, if I remember anything else, or think of anything new.
