I do not know director William Witney, never heard of him before and doubt very much that I will in the future on the strength of this mediocre effort.
The film's greatest merit is its clear photography. The script has more character inconsistencies and holes than Swiss cheese (Marla English keeps jumping from the arms of Jan Merlin to those of Ben Cooper and back, and no one seems to mind as plain-faced Joan Evans starts smooching Cooper too, for instance).
Merlin has the plum role, playing the nefarious, impulsive, trigger happy but not stupid Kutner. What detracts from a successful performance is the poor script that has him suddenly and needlessly kill a compliant security van driver, then fail not kill Cooper when he could and probably should. Although he uncovers Cooper's and Evans' ploy involving a portable radio, he fails to detect that blocked nose, constantly sniffing Nick Adams has replaced the heist dough with pine cones, and finally crazily places himself in the line of fire.
Supposed femme fatale English is not that fatal, except to herself (she gets a stiff prison sentence). Besides traveling between the arms of Merlin and Cooper, and leaving a gun for the latter to pick up and point at Merlin, English's most memorable moments involve her light clothing and high heel shoes while everyone else wears warm clothes and the snow builds up outside.
Pretty boy Cooper seems in love with English, then falls for Evans. You can see that he is the one who can do something to turn the tables on Merlin and Adams, but at the crucial moment he fails to make meaningful use of the gun English gives him. He also drives a car needlessly fast when he is not even being chased - the script never clarifies whether he is just a fast driver by nature.
Talking about Nature: the sudden change from sunny weather to snow is too improbable for words. How Cooper and the authorities track down the heist stash hidden in the snow is never explained, you just learn that Cooper and Evans are getting a reward for returning the proceeds, when a minute earlier Cooper kept repeating that he had had nothing to do with replacing the money with pine cones, and had no idea where the dosh might be.
Too many character motivation holes, not enough action, bad script. Waste of valuable time.
