All supplied casting comparisons and performer facts are normalized as unresolved; therefore no established-character race, gender, or sexuality change is confirmed and the minimum-score floor does not apply. New supporting roles are presented only as original characters without narrative emphasis on diversity as theme. Reception summaries and plot descriptions continue to highlight tension and horror rather than messaging.

Because the research record contains no authenticated progressive ideological elements, the work aligns with the 0-1 band of traditional, neutral storytelling. Material uncertainty exists around any unverified casting details, yet unresolved status prevents elevation of the score. The narrative premise, character arcs, and thematic focus stay unchanged from the supplied original analysis. Casting evidence: Casting research is incomplete or contains unresolved comparisons; overall casting fidelity has not been established.

Documented credits include Idris Elba as John Luther; Rose Leslie as Emma Lane. The casting comparison for Idris Elba as John Luther remains unresolved. The casting comparison for Rose Leslie as Emma Lane remains unresolved.
