Python script to import your Letterboxd movies into IMDb.

How it works:
The script first "visits" all the Letterboxd links in your zip file and gets the corresponding IMDb page. This way, it can be ensured the correct movie is rated.
After that, your cookie is used to authenticate a request to the internal IMDb GraphQL rating API.

required arguments:
  -f ZIPFILE   The exported zip file from letterboxd

options:
  -h, --help   show this help message and exit
  -p PARALLEL  Urls to be processed in parallel (valid: 1 to 20)
  -c           Add this flag to disable the history
  -r RATING    The rating to give watched but unrated movies. By default they are ignored (valid: 1 to 10)
  -w           Add this flag to also transfer your watchlist

-p: Can be used if you want to speed up the process, if you set it too high you might get rate limited. Default: 5
-c: If the history is causing problems, you can add this flag to disable it.
-r: Can be used to rate watched but unrated movies. Because IMDb doesn't have an option to "just watch", a default rating has to be specified
-w: Used to also transfer your watchlist

Advanced usage example: py letterboxd2imdb.py -f .\letterboxd-user-2022-02-20-16-16-utc.zip -p 10 -r 5 -w
