10 Pairs of Movies That We're Convinced Exist in Each Other's Universe (Screenrant)

"Even though they're not canonically related, there are certain movies that feel like they take place in the same world as another movie. These films are not sequels of one another & don't necessarily share the same director or cinematographer, but they have a similar mise-en-scène. Different aspects of one movie, whether it's the tone, the setting, or even the characters, share a likeness to another film, so much so that if a character from one of the movies were to show up in the other movie, they would not seem out of place. Marvel has spent years building a cinematic universe where all their films connect, & other franchises have followed suit, to a lesser extent. This tactic has proved beneficial for Marvel, helping make the MCU the highest-grossing film franchise of all time. While the following films certainly don't belong to the same cinematic universe in the same way, they have undeniable similarities that make it feel as though they exist in the same world." - screenrant.com
