How FilmCoStars finds shared movies
By Christian Himmer · Updated October 28, 2026
FilmCoStars compares the filmographies of two to five actors and returns the movies they all appear in. It is the fast answer to “weren’t these two in something together?” without opening a filmography page for every name.
Step by step
- 1
Pick the first actor
Start typing a name in the first field. The dropdown queries TMDb live, so use it to pick the exact person — two actors can share a name, and the right TMDb profile is what makes the comparison accurate.
- 2
Add the second actor
Repeat with the second field. If you want to check a whole cast, press Add Actor and go up to five people.
- 3
Run the search
Press Find Co-Stars Movies. Each actor's movie credits are downloaded and compared in your browser, not on our servers.
- 4
Read the intersection
Only films where every selected actor appears in the credited cast survive the comparison. Results are sorted from the newest release to the oldest.
- 5
Check the roles
Each card shows the character every actor played. The title links to its TMDb page, where you can confirm the full cast.
What counts as a shared film
The comparison is an intersection of cast lists. If you select two actors, a title only appears when both are credited. With four actors, all four must be in the cast — adding names narrows the list instead of widening it.
- The film must appear in the movie credits of every selected actor.
- The credit has to exist in TMDb's cast list for that title.
- TV series, miniseries and TV movies are excluded; only feature films are compared.
- The result is the intersection, not the union: a film with three of your four actors does not qualify.
Why a movie you know is missing
Four situations explain almost every “but they were in that film” moment:
Uncredited work
Cameos, deleted scenes and voice work without an on-screen credit are often absent from TMDb, so the tool cannot see them.
Archive or documentary footage
Films built from old footage usually credit the archive, not the actor. Those appearances rarely appear as cast credits.
Recent releases
A film announced or just released may still be missing cast entries. TMDb is updated by its community, so it fills in over time.
Same name, wrong profile
If you picked a namesake instead of the actor you meant, the comparison uses the wrong filmography. Re-select the person from the dropdown.
If the credit itself is wrong, it can be edited on TMDb by any contributor, and the change shows up here with the next search.
2 to 5 actors
More actors means fewer films, because everyone must be in the cast.
Live TMDb data
Every search queries TMDb from your browser, so nothing is cached or stale.
Newest first
Results are ordered by release date, so the latest collaborations appear on top.
Privacy while you search
Searches are not stored. The query goes from your browser to TMDb and the comparison runs locally, so there is no history to delete. Analytics only loads if you accept cookies in the banner, and the site works the same if you decline.
