dambusters was made in 1955 i suspect it would be difeent if it was made now.
Of course, it is a product of it’s time (and our cultural outlook). Don’t forget, US films of this sort of era (ok, maybe 10 years later) would have had John Wayne running around winning the war single handed.
If anything, recent (post Platoon?) US war films have come more into line with our outlook – futlity, failure, less whiter than white characters.
Although even last year’s Pacific had the sugar coating of following most of the men through to their everything will be ok in the end post war survival (and I don’t mean that to take anything away from the USMC survivors that were portrayed). This is one area where Band of Brothers was probably better than Pacific. BoB was far grittier in this respect.
ETA – and of course, US films almost always have to have that easy to digest, unequivocal, white vs black , good vs evil, us vs them message. US films do that to this day, whereas British films don’t tend to follow this rather sickening format
