Cloverfield (including 10 Cloverfield Lane) - I've not seen the latest one (Cloverfield Paradox). I suppose I'll have to get round to seeing it.
Pandorum - if that counts, it's really good. Almost a cosmic horror too due to it's mystery & Sci-Fi themes.
Titanic - A genuine classic & master of the disaster genre.
Threads (1984) - Schools across Britain had to watch this for decades. Me being British, I had to watch this even in the early/mid 2000s. It's a British movie about a potential nuclear war. The nuclear explosion part is old & cheesy yet extremely brutal and haunting to remember.
Terminator 2 - if that counts, the future that the terminator comes from is a world-ending disaster. The nuclear scene in that movie is also brutal like Threads' scene.
MARS ATTACK! - hahaha, I have to put this nostalgic masterpiece of magical art in a strange era that almost existed for a while, that only 90s kids would understand XD.
My favs have to be old Zombie films by George Romero & others inspired by his work-
Dawn of the Living Dead (1978)
Zombie Flesh Eaters (1979)
Day of the Living Dead (1985)
Return of the Living Dead (1985)
Return of the Living Dead part 2 (1988, there are also other parts but I wasn't a fan of the rest)
Night of the Living Dead (1990 remake)
28 Days Later (2002)
Dawn of the Dead (2004)
Land of the Dead (2005)
.Rec (2007, including all the sequels, originals & US retakes)
The Crazies (2010 remake)
...and many more that I will remember after writing this.
I need to see 28 Weeks Later. I keep meaning to watch it for years. I loved the first one. I'd probably have this in my list too if I saw it.
I would also like to mention - Devilman Crybaby (2018 remake of an older anime series). I know it's not a movie but it's a short series, but it has a shocking ending fits perfectly into a dark theme of global disaster. It's an ending that always stays in my mind.
I enjoyed writing this. I agree with others posts here too. The Day after Tomorrow, 2012, I am Legend, Shawn of the Dead, Zombie Land. I enjoyed them all even if 2012 got a bad reputation at the time. It came out when global weather disasters where influencing Hollywood to make so many relatable films which made it feel run-of-the-mill, then using constant CGI for the awe-factor & having generic characters that are universally understood by millions across the world to boost sales, etc. But I like the disaster scenes & special effects. I still watch clips of it now.
