Ambush is a tight, well-paced western, expertly assembled by veteran director
Sam Wood, whose last film this was.
Robert Taylor stars as an Indian scout, sent to rescue a woman who is somewhere deep in Apache territory. The woman's sister, naturally, goes along for the ride: she is played by
Arlene Dahl, then in her considerable prime. Outside of its feminine angle, Ambush is packed with action from first frame to last. Released to theatres at the tail end of 1949, the film was an unqualified success with holiday audiences. ~ Hal Erickson, All Movie Guide
