Actors whose show travelled draw 3× the lookups. Hold two things fixed and most of that disappears.

We keep two tables that have never been put side by side: which countries a Korean title charted in, and how often people opened its actors’ English Wikipedia pages. Joining them through Wikidata cast lists gives 979 Korean actors who appear in both.

The first number out is large. Actors whose best title reached 20 countries or more draw a median 4,759 lookups over 30 days, against 1,542 for everyone else — 3.09×.

That number is mostly wrong, and the way it is wrong is the point.

Hold the amount of work fixed

An actor with five charting titles draws more lookups than an actor with one, whatever those titles did. So the comparison has to happen inside a band of actors with the same amount of work.

Two of the four bands collapse to almost nothing. The last one does not, and that is the row worth attacking.

Hold recency fixed too

Titles that reach many countries are disproportionately recent, and a recent title lifts lookups now. So each band splits again by whether the actor’s most recent charting week falls after 2025-08-01.

The objection takes the biggest number away. Among actors with five or more charting titles, reach is worth 4.06× if they charted in the last year and 1.11× if they did not. The bottom row of the first table was telling us when these actors last worked, not how far the work went.

What survives

The first row. For actors with a single charting title the ratio holds on both sides of the recency split — 2.37× and 1.94×. One title that reached twenty countries goes with roughly double the lookups of one title that did not, and that holds whether the title charted this year or three years ago.

It is the group where the join can say the most, because it is the group with the least else going on: one credit, one outcome.

The cell that runs backwards

Actors with exactly two titles, charting recently, show 0.68× — the actors whose title travelled were looked up less. We are not going to explain that. With 34 actors on one side and 31 on the other, a ratio of two medians is not a finding; it is what noise looks like at this size. We print it rather than tidy it away, and every cell below 12 actors a side is marked too thin to say instead of being given a number.

One more hole worth naming: cast lists are attached to 635 of the 901 charting titles, so 266 titles carry no actors here at all. An actor whose only credits sit on those is absent from this piece entirely — not counted as low, just absent.

What a casting director should not take from this

Not that hiring an actor whose show travelled will make the next show travel. Direction is not established here and cannot be — a travelling title may raise a profile, or a known face may be cast into titles that were always going to travel. What the join does show is that the 3.09× headline is roughly two parts bookkeeping to one part signal, and that anyone quoting it without the two controls is quoting an artefact.

The full table, both controls, and every cell we refused to put a number on: actor reach.

What this does not say: that these actors are liked, or that anyone watched anything. A Wikipedia page opening is a page opening — it climbs for a wedding and for a lawsuit alike, and we count openings and never the reason.
