Jimmy Stewart gets top billing and a lot more screen time than fellow mega-star Henry Fonda in this early modern western. 59 years old when the movie was being shot, Stewart looks if anything even older as remarked by many others. He is NOT credible as a new father even of his third child.
Fonda was three years older but has aged much better, looking fit, competent, credible even as a love interest for Inger Stevens who is just about half his age.
This movie is driven by character. The story is simple, not very original and quite slow to get going. However, and as one perceptive reviewer noted, Gary Lockwood's performance as a drawling, baby-faced killer is superbly convincing. His character shows a surprising self-possession, too, always giving part- time sheriff Stewart an excuse to keep looking the other way. It makes him dangerous to everyone, the boss of the outfit (Fonda), especially. Veteran western actor Jack Elam--later to appear in a soft drink commercial-- is no self-parody here! Tough, cunning, mature, his character is just amoral enough to be part of the crew of hired guns that the town of Firecreek has the ill luck to play host to.
In this age of dumbed-down scripts, mumbling actors and dialog that rambles on for no apparent reason, the articulately spoken, sharp and memorable lines given to all the characters is a poignant reminder of what movies used to be. They most of all are what make every minute of this picture worth watching.
