The top 10 neighbors for Julianne Moore span book publishers, politicians, government officials, news publishers, and fellow actors — a mixed cluster with no single subcategory dominating and scores compressed between 0.91 and 0.93. Similarity here measures how closely two entities' audiences resemble each other in composition; a score of 0.93 indicates very high overlap.

The leading neighbor is NY AG James at 0.93, a Government entity — not an actor, not a film-adjacent brand. Alongside it sit Chuck Schumer (0.92, Government Officials) and Jerry Nadler (0.92, Politicians), making political figures a notable thread through the top 10. Book publishers form the other major strand: Penguin Random House (0.92), Alfred A. Knopf (0.92), and Simon & Schuster (0.91) all appear, with NYRB Classics (0.91) rounding out the publisher presence. News publishers contribute The Globe and Mail at 0.92.

Three neighbors share Moore's own subcategory of Actors: Jane Fonda (0.92), Mia Farrow (0.91), and Patricia Arquette (0.90). That's a meaningful presence, but actors are outnumbered by the combined weight of publishers, politicians, and government figures — meaning the audience shape here is defined as much by civic and literary engagement as by film fandom.

The flat shape reflects a cluster where no single neighbor pulls away from the pack; the audience overlaps broadly and evenly across political, literary, and acting spheres simultaneously.
