Letterboxd Localized

Letterboxd Localized enhances your Letterboxd experience by
pulling localized data from TMDB and displaying it directly
on the pages you browse — no tab switching, no copy-pasting.

FEATURES

Localized titles
Translated titles appear on poster tooltips, film pages and
review headers. Useful when browsing lists with films from
other countries.

Localized synopsis
The film synopsis is replaced with a localized version in
your chosen language. A toggle lets you switch back to the
original at any time.

Cast photo grid
The top 10 cast members are displayed with their photos
above the standard Letterboxd cast list.

Streaming availability
A streaming panel shows where the film is available in your
country (subscription, rent or buy), pulled from TMDB and
filtered by your selected language region.

Localized trailer
A trailer link appears when a version exists in your
language on YouTube. If no localized trailer is found,
nothing is shown.

Subtitle search
A direct link to OpenSubtitles opens a pre-filtered search
using the film's IMDb ID and your selected language.
