I've recently been updating my library of movies to use the theatrical posters. It seems in the last ~10y or so there's been a bunch of "remade" posters for old movies---I presume from Netflix trying to get people to click.
It's neat to sort the movies by time and see how the styles change. Makes it feel more real than when each cover has the same modern look.
Out of curiosity as someone who might like to do something similar: what sources and workflow do you prefer for this process?
