This western is well directed and smartly acted by all involved, but the stand out performance is Tab Hunter's role as the oldest son, Ed. The story begins at the point of our witnessing the finality of Ed's hatred and idolatry of his father, a hard-as-nails, always-has-to-be-better-than-his-sons kind of man. Ed is wound so tight that he has little give for anyone.
This performance reminds me of Denzel Washington's Oscar winning role in Glory. As the story goes along, more and more nuances are revealed that show the depth of the character. I watched Glory three times before I caught the depth in that character that deserved an Oscar. I have watched Gunman's Walk twice and saw more depth in Hunter's character the second time. It's a fascinating role (maybe Hunter was drawing from the anger he felt for having to hide himself within the Hollywood treatment he underwent) and I don't think anyone could have played Ed any better.
It is a shame when such levels of acting come out of actors not expected to do so brilliantly, because they don't get their just recognition, kind of like Val Kilmer's Doc in Tombstone. Hunter was the beefcake, male blond beauty presented in such a manner by Hollywood. He wasn't expected to actually act well, they didn't even consider it (and he didn't do very well with most of the movies they put him in). When you read the biography of Hunter given here on IMDb, Gunman's Walk isn't even mentioned. The focus is on his Hollywood image.
Hunter's Ed is well worth the look. Heflin's Lee (everyone calls him Lee, including his sons) is very well acted and, but for Hunter's performance, shines as the gregarious, tough, but flawed father who had no idea how to raise his sons. In the scenes the two are together, the tension is always there and they play off each other well.
All the acting is done well (Bert Convy's ability to ride a horse well is suspect, though). The movie is tightly directed, the action is constant, and there are no scenes that will lull you to sleep. If you like westerns with tense action and flawed characters, you won't be disappointed with Gunman's Walk.
