Play Dirty
There's no mistaking the 1968 mood of Play Dirty: this cynical war movie could only have been made during the disillusioned Vietnam era, despite its WWII subject. Michael Caine plays a British captain in North Africa, tapped to lead a suicidal mission across the desert to destroy a German fuel depot. He's got a scurvy band of mercenaries to help him (this was a year after The Dirty Dozen, so keep that in mind), although most of the time they seem indifferent to both the job and Caine's survival.
