All ten of Cobie Smulders' nearest neighbors are actors — a uniformly same-kind cluster with no cross-category entries in the top 10. Similarity here measures how closely two entities' audiences resemble each other in composition; scores across the top 10 span a tight 0.85 to 0.80, consistent with the broad shape classification.

Sarah Hyland leads at 0.85, followed closely by Alyson Hannigan (0.84) and Emmy Rossum (0.84). Emma Watson (0.84) and Zooey Deschanel (0.83) round out the top five. The scores compress quickly — Brie Larson at 0.81, Seth Rogen at 0.81, Chris Colfer at 0.81, Neil Patrick Harris at 0.80, and Simon Pegg at 0.80 — with no single neighbor pulling significantly ahead of the rest. That narrow band across ten positions is the defining structural feature: no spike, no outlier, just a dense pack of actors whose audiences all look roughly alike.

The absence of directors, musicians, comedians, or non-celebrity entities in the top 10 reinforces how tightly this audience maps onto the actor subcategory specifically, rather than entertainment broadly. The wider graph at positions 11–50 may introduce more category diversity, but within the top 10 the shape is unambiguous.

This is an audience that tracks actors as a type, not a genre or franchise — the breadth of the cluster reflects mass-market reach within a single, well-defined kind.
