The top 10 neighbors for Will Arnett form a tight, mixed cluster of comedians and actors — no single neighbor pulls far ahead of the rest, and the scores compress into a narrow band from 0.96 down to 0.94.
The shape is flat. Jemaine Clement leads at 0.96, followed closely by Arrested Development (0.95, a TV show), Andy Richter (0.95), Bob Odenkirk (0.95), and Sarah Beattie (0.95). Tallying the subcategories across all 10: five are Comedians (Jemaine Clement, Andy Richter, Sarah Beattie, Colin Jost, Nick Kroll), three are Actors (Bob Odenkirk, B.J. Novak, Allison Janney), one is a TV Show (Arrested Development), and one is an Athlete (Megan Rapinoe at 0.93). The dominant pattern is comedians and actors in roughly equal measure — a cross-subcategory mix that sits close to Arnett's own Actor subcategory without being dominated by it. Megan Rapinoe is the only non-entertainment figure in the top 10, and the only Athlete; no other sports figures appear in this set.
The overall picture is an audience that moves fluidly between comedy-adjacent performers and dramatic actors, with no single neighbor or subcategory commanding a clear lead.
