Nathan Fillion (0.80) and Chris Pratt (0.79) form one clear peak in Sean Astin's top 10 — both actors, both pulling nearly identical scores — while a second, distinct cluster anchors around Weird Al Yankovic (0.76) and Foo Fighters (0.74), two Musicians and Bands neighbors that sit noticeably apart from the actor-heavy lead. That two-peak structure is the defining feature of this similarity map.

Tallying the top 10 by subcategory: six are Actors (Fillion, Pratt, Ryan Reynolds at 0.72, Wil Wheaton at 0.72, Tony Hawk at 0.72 — wait, Hawk is Athletes — and Macaulay Culkin at 0.71), one is Athletes (Hawk, 0.72), two are Musicians and Bands (Yankovic and Foo Fighters), one is Comedians (Dane Cook, 0.73), and one is a TV Show (Doctor Who on BBC America, 0.70). The actor cluster dominates, but the musicians sit high enough — both above 0.74 — to constitute a genuine second neighborhood rather than background noise. The comedians and the lone TV show entry round out the set without forming a third cluster of their own.

What this shape suggests is an audience that overlaps strongly with fans of genre-adjacent, convention-circuit actors, but also carries a meaningful contingent whose shape tracks with rock and novelty music fandom — two distinct communities sharing the same audience profile.
