Two distinct tiers define Ben Affleck's similarity neighborhood: a tight cluster of fellow actors at the top, and a secondary band of non-actor entertainment entities just below it. Similarity here measures how closely two entities' audiences resemble each other in composition — a score of 0.93 means near-identical audience shape.
Leonardo DiCaprio (0.93) and Mark Ruffalo (0.93) sit at the peak, separated by less than a point and well above the rest of the field. Below them, a run of actors — Eliza Dushku (0.90), Dianna Agron (0.90), Kevin McHale (0.87), Chris Colfer (0.84), Cara Delevingne (0.84), and Alyssa Milano (0.83) — extends the actor cluster through eight of the ten positions. The second peak emerges at the lower end of the top 10: Wonder Woman 1984 (0.84) and The Killers (0.83) break the actor pattern, representing a Movie Franchise and a Musicians and Bands entry respectively. These two non-actor neighbors cluster together in score and in kind, forming a distinct secondary neighborhood rather than isolated outliers.
The overall shape is an audience that maps overwhelmingly onto other actors, with a secondary pull toward franchise film and music properties at the margin.
