This scene, I submit, contains one of Henry Fonda‘s greatest acting moments. It’s from William Wellman‘s The Ox-Bow Incident, of course — a 1943 film, set in 1880s Nevada, about a lynch mob looking to avenge an uncomfirmed killing of a well-liked local rancher. Fonda plays Gil Carter, the former boyfriend of Rose Mapen (Mary Beth Hughes) who has recently married a snooty San Franciscan named Swanson (George Meeker). Watch Fonda’s gradually shifting reactions to Swanson, particularly starting at the 1:40 mark. That very slight tilt of the head at 1:45…perfect! Fonda was 37 at the time of filming. Jane was about five; Peter was two or three.
