David Harbour Is Ready to Talk About His Mental Health, Lily Allen's 'West End Girl' and the End of 'Stranger Things'

David Harbour's transformation for DTF St. Louis centers on a modest physical adjustment, including a prosthetic belly to portray Floyd Smernitch as a pudgy Midwestern dad. The actor notes that the change helped him wear a mask and perform with looser, more buoyant movement in dance scenes. Floyd sits at the center of a morose, yearning drama framed by a murder-mystery setup and a triangle with Clark and Carol. The show derives its name from a fictional dating app used by the characters, and it uses flashbacks to excavate longing, angst, and suburban shame. Created by Steven Conrad, the project asks Harbour to balance tenderness with vulnerability as the story deepens.

Harbour's work is described as a blend of emotional intelligence and physical staging, allowing the world to feel intimate and expansive. Conrad and Harbour collaborated closely, shaping Floyd's arc from development through performance. DTF St. Louis has emerged as a focal point in Harbour's career, placing him in Emmy contention after prior nominations for Stranger Things. The evolution of Floyd—along with wardrobe and posture—illuminates themes of identity and the elusive American dream.
