Alistair Mc Lean was definitely the true and authentic DNA provider of the action action packed movies huge, gruesome wave that we saw in the nineties and till the late twenties, and which many folks told it was all DIE HARD rip offs. You also had Walter Wager - whose 58 MINUTES inspired DIE HARD 2 - and Colin Forbes, who gave us tremendous novels about terrorists and spies, action thrillers that riveted you to your sofa. Well all those stories were not always top but worth though. This one is not the worst, far from that. Worth and not the worst. And I would add that film takes advantage of the disaster movie 'fashion" of the seventies to mix it up with the scheme of terrorists and hostages. One last thing, no one seems to have noticed that Dick Harris gives here a performance very close to the one he pulled in another sea thriller, about another terrorist plot, the terrific JUGGERNAUT, where he faced David Hemmings.
