Alistair MacLean wrote an original screenplay that was treated with respect for the writer's unusual abilities as a master of actionful suspense. The resulting film is highly entertaining, thrilling and rarely lets down for a moment.
It is so long (almost three hours) that it may finally bore the very action trade for which it was intended; yet it's just at that point of surface boredom that the movie aficionado will probably become entranced.

You have to admire any film that casts Clint Eastwood opposite Richard Burton; the real violence is in the clash of acting styles.

...it provides full-on thrills, maybe exaggerated thrills, to be sure, but making for an exciting ride, nonetheless.

A straight-ahead, old-school action movie for war-espionage junkies. [Blu-ray]

If it's a mindless roller-coaster thrill ride that you fancy, this is the vehicle that knows how to make it a fun ride.
