It’s here: backdrop customization. our Patron tier, you’ll be able to pick a custom backdrop image for any film, and separately change the image on your reviews, diary entries, lists and profile.
Along with customizable posters and cast and crew photos, backdrop changes give Letterboxd Patrons another avenue to express their singular tastes and personalities on their respective pages. An example: when the poster feature dropped, my first act was to change the poster of every movie starring Robert Pattinson to include his face, no matter how small his role. I intend to do the same for backdrops.
