What are some good group of "Unrelated/Non Sequel Shared Universe Movies"

I think the topic might be confusing, but I am looking for unrelated movies that are not directly related to each other in a manner that they are sequels, remakes or reboots. So when u watch them in a particular sequence (or not) it makes much more interesting. I would like to give one example each from fiction and based on real events.

For 9/11 related stuff - Charlie Wilsons War, United 93/World Trade Centre, Vice, Zero Dark thirty, The Mauratian, The Report.

The Last Voyage of Determir, Bam Stokers, The Dracula, Interview with a Vampire

What are some other such combinations of movies.
