At 0.93, Robert Kirkman — an author, not an actor — sits at the top of Steven Yeun's similarity graph, just ahead of a dense cluster of actors. That gap between the two peaks is the structural story here.

The shape is two-peak. Kirkman (0.93) forms one pole; Jon Bernthal (0.91) anchors the other, leading a tight band of seven actors that includes Melissa McBride (0.89), Emily Kinney (0.87), Katey Sagal (0.86), Chandler Riggs (0.86), Norman Reedus (0.86), and Sonequa Martin-Green (0.85). AMC Networks (0.86, TV Channels) sits within that actor cluster, reinforcing the franchise-level coherence of the group. The one outlier in the top 10 is IPSY (0.85, Beauty) — a brand with no apparent thematic connection to the rest, whose audience shape nonetheless lands squarely inside this neighborhood.

The overall picture is an audience defined almost entirely by a single franchise ecosystem, with a comic-book author pulling slightly ahead of the cast itself — and one beauty brand whose audience composition mirrors the whole group.
