Mitchum was let out of jail to film this Don Siegel road movie, on probation after being charged with possession of dope, and looks the part. The only other film he made with Jane Greer, 'Out Of The Past', made it clear the pair had chemistry, and in this film they squabble pretty much until the final big smile for the camera shot.
It's a neat much ado about nothing caper, Mitchum and Greer pursuing a flim-flam man, Fiske (Patric Knowles) and his suitcase of cash, while being pursued in turn by Captain Blake (William Bendix), enraged that Mitchum has been impersonating him and stolen his passport. A Mexican police caption almost outwits them but in the big showdown the pair, unlike their counterparts in 'Gun Crazy' (aka. 'Deadly Is The Female', 1950), get away with their big steal.
The DVD includes a colourised version (faces and backgrounds tinted pastel shades) which is of interest only to illustrate how the movie's classy look derives in large part, not merely from its era but from its form: in black and white it has great style, colourised that style is harder to see and the film looks more like the cheapish production that it probably was.
The pace at which the scenes are played, the beauty of the two leads, the thrill of a road movie going down deep into Mexico (The Getaway, Three Burials, Y Tu Mama Tambien) and the easy nonchalance, the controlled recklessness that Mitchum brought to any part, together with the beauty of Jane Greer, the whole thing has something of the charisma of 'To Have and To Hold'.
