One Minute to Zero (1952)

Plot:  In 1950 Korea, an idealistic UN official (Ann Blyth)  discovers the horrors of war when she helps a hard-bitten US Colonel (Robert Mitchum),  evacuate South Korean Refugees.
Stars: Robert Mitchum, Ann Blyth,  William Talman, Charles McGraw

Produced by Howard Hughes at the height of the Korean War, the movie is a solid, if somewhat predictable,  war programmer notable for its good use of war footage and  US Military equipment.  With a few exceptions the combat scenes are well done, especially a tense scene where Mitchum has to fire on a column of refugees. Talman, who always looked 10 years older then his actual age, lends adequate support.  Blyth does as well as she can with an underwritten role and perfunctory romance with Mitchum.

Summary:  Although almost forgotten, One Minute to Zero is worth a  look if you're interested in the Korean War or just enjoy war movies.  The low 5.8 IMDB rating seems to be due to politics. The movie is just too darn anti-communist for several left-wing critics.  The movie should have "balanced things out" they say - a criticism never made of WW 2 movies. Based on my readings, the story is fairly accurate, but its film -not a history lesson.
