Space constraints will "finish" my collection unless I purchase a big DVD wallet to compress the collection 🥲. I class releases as different regions, if they're director cuts and sometimes if the old first releases of that movie have scenes still in them.

Home Alone 2 is one I think of instantly, They used trump tower for the hotel lobby and he just had to be in the movie for them to be allowed to film there. It's been cut out in later releases, sometimes it's added as an extra.
