About Collections

Letterboxd Completionist is a user-made project that shows which film collections a Letterboxd user is close to completing. The user exports their Letterboxd data, uploads the watched.csv file, and the tool processes it against its collections list. Results then appear on the same page.

The source notes that Letterboxd Pro members can see completed collections on their stats page, but that page does not show collections nearly finished. The project fills that gap and says it can also help users find something new to watch. The collections data is not live. It was last updated December 13, 2020, and the project uses elements from Letterboxd and TMDb.
