If I may nit-pick a particular paragraph, the author wrote that the original Raiders jacket was unmothballed, tried on by Ford, and was then recreated, stitch-for-stitch.A very good theory. And now we know that you are at least partially right! In the latest drip of new information, it is revealed that the all important opening sequence is a flashback to a fight against Nazis in a castle in 1944.
The issue: Raiders took place in 1936. LC took place in 1938, with a subtly different jacket. The flashback in the the new movie is supposed to be in 1944, which is six years after LC. So why go back to an 'eight' year old, most likely worn out jacket?
Nit-picky, yes. Would it really matter, though, exactly which jacket style they used? The HAT is what's most important! hahaha
