Like all of Don Siegel's movies we are immersed in the action from the beginning of this spectacularly shot mystery thriller.Not a single frame,word or gesture is wasted just like in all of Don's films.No wonder Clint Eastwood attributes his own economical movie-making style to him. Cornel Wilde's deputy sheriff carries the whole film very well like in a old school noir mystery he is in almost every scene piecing the puzzle along with us and we are not given any information other than what he learns therefore the final revelation is as shocking to us as is to him. Like of all Don Siegel movies the supporting cast is great; including the late and great Edgar Buchanon, Siegel regular Jack Elam and the very beautiful and charming Victoria Shaw.But like in all his films the bad guy (revealed at the end)is awesome. Kudos to Don Siegel ,one of my all time favourite directors. Special mention has to be made of the film's stuntmen's work in the climax.I won't spoil it but it's a nail biting sequence.
