About FilmCoStars
By Christian Himmer · Updated October 28, 2026
FilmCoStars is a small, independent tool for one very specific question: which movies did these actors star in together? You pick two to five names and the site returns the films where all of them appear in the cast, with the character each one played.
Why it exists
Answering that question usually means opening a filmography page for every actor, scrolling through hundreds of credits and comparing lists by hand. FilmCoStars does the intersection for you in a couple of seconds, so the fun part of the conversation stays intact.
The project started as a weekend build and is maintained by a single developer. It is free to use, has no accounts and does not ask for personal data.
How the data works
Every title, poster, release date and character name comes from TMDb (The Movie Database), a community-maintained database. When you search, your browser asks TMDb for each actor's movie credits and we compare the results locally. Nothing is stored on our side.
This product uses the TMDb API but is not endorsed or certified by TMDb.
Films only
Feature films, not series or TV specials.
2 to 5 actors
Everyone you add must be in the cast.
No accounts
No sign-up, no email, no stored searches.
Corrections and contact
If a credit looks wrong, it is almost always a TMDb data issue and can be fixed there by editing the title. For anything about this site, suggestions or bug reports, write to contact@filmcostars.com.
