This is a typical 1950s British war film. The music sounds very much like "Bridge over the River Kwai" and that's not surprising as its the same Malcom Arnold. His music always seems to have a grand intensity to it. Great movie symphonic scores.
This is a reinforced British Recce Section packed with some future power houses in acting. Robert Shaw, Michael Caine are in the thick of it with Harry Andrews and Stanley Baker. All you need is a Gordon Jackson to add a Scots element to the Squad. Caine was probably the only one who had seen active service with the Royal Fusiliers in Korea. He was hired on as both an extra and a military advisor. His role is even smaller than Shaw's who gets at least to wax lyrical about farming before he gets it chopping up the Chinese with the Bren Gun.
Most Americans assume that the US Marines fought the Korean War. This film should be made available in the US to prove otherwise. While the UK/ Commonwealth involvement was limited to a Division or so they fought some famous actions. The Black Watch fought a celebrated action at the Hook helping out US Marines, and of course the Glorious Glosters made their famous last stand at the Imjin River.
The Squad we have here must be outfitted from later in the war as there are a lot of automatic weapons. At least four Brens chop up the Chinese early on. The crude human wave methods of the Reds are pretty horrifically shown here. Now there may be be some faults over all in this film, and its a bit chatty at times, but over all this is a classic squaddie war film. Many today might be upset by the liberal use of "Chink" and "Gook" references by all the characters but this was made not long after the events depicted and no doubt reflected public sentiments at the time. Still, PC types should be aware. Also, there is a big plug here for the national servicemen who filled out the ranks of the regulars in this conflict. Very interesting film and great for all the future actors in it.
