This is John Sturges' movie. It is beautifully directed, with some shots that are truly stylistic, artsy, and beautiful...all the more so since this is in black & white and one can enjoy the symmetry of the shots instead of running the risk of being distracted by vibrant colors.
The cast is loaded with big name B stars and is more of an ensemble piece than a traditional Randolph Scott film. Scott has some of his nicest on-screen moments in this film, along with the always fantastic Edgar Buchanan. Two actors I had never seen before, Jerome Courtland and William Bishop, both give very good performances...especially Courtland. John Ireland, and even moreso Arthur Kennedy, are completely wasted in roles that are one-dimensional and truly go nowhere. The worst of the entire group is Ella Raines. She is not a strong actress, had no chemistry with either Scott or Bishop, and there was really no reason for her to be in the film at all.
This leads me to the script, which is where the movie falls down...it is a collection of missed opportunities. The plot is simple, the motivations extremely flimsy, the tension non-existent, and the ending unsatisfying. A similar "group stuck in the desert" film, James Stewart's version of "Flight of the Phoenix", had some real uncomfortable moments, surprises that worked, deaths that we felt, characters we were interested in, plot twists that pulled us to the edge of our seat...and their group was all focused on a common goal! In "The Walking Hills", the group is ostensibly working toward the same goal (uncovering the gold), but there is the added plot element that they are actually competing against each other at the same time. That element is never fleshed out in a satisfying way. The relationships don't go anywhere, the conflicts never reach a crescendo, the plot twists fizzle out, the promise of double-crosses and triple-crosses never materialize, everyone's hidden agendas don't pay off as they should, and out of the entire group only one character has any kind of arc where something is learned, personal growth takes place, and he is a different person by the end of the film. It's just a boring trek through the desert, with lots of digging, and not a lot of much else going on.
Actually, one other thing does go on: a lot of singing. Fortunately, it's good singing. Josh White sings a few original songs and accompanies himself on the guitar. They are pleasant songs, but do not move the plot along, reveal character elements, or underscore on-screen action, so they are strictly time-killers meant to draw out the running time. As musical numbers, they are fine, but they certainly do nothing to advance the film.
"The Walking Hills" is not what I would necessarily call a bad film...it's just an uneventful so-so experience. As stated, several of the actors do have a moment or two where they shine, and the directing is beautifully done, but the film on the whole is a bit of a dud. Randolph Scott, Edgar Buchanan, and John Sturges fans will enjoy this, others will fall fast asleep.
