Lupino does a fantastic job. A lean and mean thriller about a murderous hitch-hiker who makes a couple of regular guys drive him across the deserts of Mexico. The technical aspects are impressive, great lighting and editing and staging. The mood and the story are tense, and Talman's vicious streak cuts like a knife. The one weak point is that it's one of those movies where you keep thinking "well, what *I* would do is...." But it's fine if you just go along with it.
