Karen Gillan's top 10 neighbors are a dense cluster of actors, cult-franchise figures, and genre-adjacent brands — with scores spanning only 0.83 to 0.79, a narrow band that defines the flat shape.
Six of the ten neighbors carry the Actors subcategory: Robert Downey Jr (0.83), Jason Mewes (0.83), Seth Green (0.82), Tom Hiddleston (0.81), Bruce Campbell (0.80), and Clark Gregg (0.79) — meaning the audience shape is largely self-similar to Gillan's own subcategory. The remaining four neighbors diversify the picture without disrupting it: Kevin Smith (0.82) is a Director; Star Wars (0.81) is a Movie Franchise brand; Doctor Who on BBC America (0.80) is a TV Show; and Weezer (0.79) is the lone Musicians and Bands entry in the top 10. The presence of two genre-franchise properties — one film, one television — alongside a cult-adjacent band suggests the audience composition extends beyond actor fandom into a broader geek-culture orbit, even as actors remain the dominant neighbor type.
No single neighbor pulls decisively ahead; the flat shape means the audience overlaps broadly and evenly across this cluster rather than concentrating around any one figure or property.
