About CastLantern
Start with one movie or series you enjoyed. Find something new through the actors who connect them.
Discover through familiar faces
CastLantern is open to try without an account. Choose a movie or series you loved, discover shared-cast connections, and refine your shortlist. CastLantern is free to use.
Catalogue details, ratings, cast credits, artwork, and announced episode dates can be incomplete or change. Confirm the matching title, current offers, and any purchase or subscription terms on the provider’s website.
How the connections work
CastLantern looks for shared cast, then lets you refine the results with actor and genre exclusions. Titles you select, mark watched, or dismiss are left out of recommendations.
The actor search is balanced across your favorites. The order you add those favorites does not set their search priority. Results are then ordered by community rating.
Main and supporting cast are estimated from available cast and TV episode information. This is an approximation, not a measurement of screen time. Extended cast includes more incidental appearances. Recommendations come from a bounded set of discovered titles, so the results do not cover every possible match.
What the scores mean
Live scores are Trakt community ratings out of 10, with vote counts shown on recommendation cards. Titles with at least 100 votes appear first, followed by early ratings with fewer votes, then unrated titles. Rated groups sort by score, then vote count and title.
The vote threshold is a product choice, not a guarantee of quality. Preview scores are illustrative examples and are labeled separately.
Data and artwork credits
CastLantern uses Trakt but is not endorsed or certified by Trakt.
Live title, cast, community-rating, artwork, and episode-schedule information comes from Trakt. Posters and actor images are served through CastLantern’s cache. Artwork belongs to its respective rights holders.
Watch-option links open a country-specific search on JustWatch. Confirm the matching title and current offers there. The JustWatch search link earns no commission. Any separate paid referral links are identified where they appear; referral payments do not change recommendation order.
Your choices and data
Accounts are optional for discovery. Saving picks uses ChatGPT sign-in. New-season email alerts require a confirmed opt-in subscription. Signing in or loving a series does not subscribe you to email. Advertisements and public comments are not enabled.
