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.

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.

It may be devoid of significance of any sort, but it is nevertheless passably entertaining, and certainly better viewing than most MacLean adaptations.
Clint Eastwood and Richard Burton team up for a fairly high-flying adventure.
Non-stop action of the highest quality.
