An unforgettable movie that is as important and as powerful today as when it was first released.
Shute took his title from a stanza from T S Eliot's The Hollow Men:-
In this last of meeting places
We grope together
And avoid speech
Gathered on this beach of the tumid river...
The tumid (swollen) river is metaphorical, as is the beach, given that Eliot's bleak, desolate landscape is a spiritual one, as in his classic work, The Wasteland.
Shute's movie is utterly compelling all the way through, partly due to the subject matter, helped along by a stunning cast, and very capable production and direction.
The scene in which the Sub arrives in the US to check on the erratic morse signal was actually shot in Australia, as they could not obtain permission to film it in the US.
There was a very creditable 2000 Showtime version with Rachel Ward and Armand Assante, which was truer to the book, although set closer to present time, but the Peck version is still the definitive one.
You cannot top this movie for dramatic content, brilliantly delivered by Peck, Gardner, Perkins and Astaire above all.
Yes, this could still happen, and yes, nuclear deterrence may well have worked so far, but I always remember a line from Bob Dylan's "If God's On Our Side", which goes...
If God's on our side,
He'll stop the next war...
Maybe he did.
