Nine of Alan Tudyk's ten nearest neighbors by audience similarity are fellow actors — a same-kind concentration that leaves almost no room for anything else in the top 10. Similarity here measures how closely two entities' audiences resemble each other in composition; a score near 0.90 indicates near-identical audience shape.
Wil Wheaton leads at 0.91, followed by Nathan Fillion at 0.86 and Felicia Day at 0.84 — all actors. Patrick Stewart (0.82) and Brent Spiner (0.81) extend the run, with Jonathan Frakes close behind at 0.81. The subcategory pattern within that actor cluster skews toward science fiction and genre television: Stewart, Spiner, Frakes, and Mark Hamill (0.80) all carry strong associations with franchise properties, while Zachary Levi (0.80) rounds out the actor set. The one departure from the Actors subcategory is Adam Savage, a TV Personality at 0.80, and the sole non-actor in the top 10. Mystery Science Theater 3000, a TV Show, lands at position 10 with a score of 0.80 — the only non-celebrity entity in the set.
The shape flag is broad, and the scores confirm it: the gap between first (0.91) and tenth (0.80) is narrow, meaning no single neighbor dominates and the audience overlap is distributed evenly across a tight cluster of genre-adjacent actors and one cult TV property.
This audience shape is defined almost entirely by its own kind — actors with genre and franchise credentials — with almost no cross-category signal in the top 10.
