Has there been a better jump-cut than the one from Marie Windsor vigorously filing her nails to a railway engine's going full pelt along the track?
This is but one of the many delights of the seventy minutes which find her - a gangster's widowed moll - aboard a train in the company of policeman Charles McGraw who is there to protect her from mobsters hellbent on preventing her from testifying before a Grand Jury and producing a list of top-notch firms implicated in widespread slayings and corruption.
A train always heightens drama, and there is no higher one than this masterpiece, directed by Richard Fleisher (whose memoirs are a fascinating read).
One could quote some of the fast and salty dialogue but it is better springing from the lips of the cast than this keyboard. A treat in store - however many times you watch it.
