Two neighbors sit nearly level at the top of Seth Green's similarity graph — Bruce Campbell at 0.89 and Kevin Smith at 0.89 — and together they define a two-peak structure that bridges cult-horror fandom and indie-film geek culture.
The shape is two-peak, meaning the audience doesn't consolidate around a single pole but instead spans two distinct neighborhoods. Campbell (0.89) and Smith (0.89) are the anchors; Jason Mewes at 0.84 reinforces the Smith cluster, given his long association with Smith's filmography. Karen Gillan at 0.82 and Weezer at 0.81 extend the set in slightly different directions — one toward genre-franchise fandom, the other toward a specific strain of late-'90s alternative culture. Tallying the top 10 by subcategory: six are Actors (Bruce Campbell, Jason Mewes, Karen Gillan, Felicia Day, Sarah Michelle Gellar, Joe Manganiello), one is a Director (Kevin Smith), one is a Musicians and Bands entry (Weezer), and two are TV Shows (South Park at 0.78, Doctor Who on BBC America at 0.78). The actor-heavy cluster is consistent with Seth Green's own subcategory, but the presence of Smith — a Director — as a near-equal anchor, alongside two genre TV properties and a band, signals that the audience is organized around a sensibility rather than a single professional category.
The overall picture is an audience shaped by overlapping genre-entertainment loyalties — cult film, sci-fi/fantasy television, and a specific era of alternative music — rather than by any one corner of the entertainment landscape.
