Movie map: Knock Knock

A movie map shows films as connected points instead of a list. The film you pick sits in the middle, the films its viewers most often watch next sit around it, and their own closest matches form an outer ring, so you can follow the links from movie to movie. (A movie map can also mean a map of filming locations; this one maps how films connect.)

The closest films to Knock Knock (2021) are The Glass Key (1942), Hostile Takeover (2025) and Detective Chinatown (2015). 16 more sit one step further out.

The film in the middle links to the films its viewers most often watch alongside it (from Trakt, or TMDB’s recommendations when Trakt has none). Each of those links to its own closest matches, which form the outer ring. A film reached from several directions sits between them.

Yes. It’s free, with no account or sign-up, and works on phones too. On a phone, or with reduced motion switched on, the same films are shown as lists.

A list stops at one step: films like the one you searched. The map also shows the films two steps away and which film links them, so you can see why a recommendation appears and keep going. For a ranked list with a reason for each pick, use Movies Like Knock Knock.
