Don't confuse conspiracy "theorists" with facts.
Remember, it's impossible to prove a negative.
Just watched an extremely well made movie about World War I. They used film from the Imperial War Museums archives. Although it took over three years, the Peter Jackson team was able to clean up the old film with tons of software and human work. They used professional lips readers to transcribe what some of the soldiers were saying and used actual WWI survivors to speak the words. They colorized some of the images magnificently! An amazing, time consuming effort. Well worth viewing, if you can find it. My point is, there will be some who will try to foist the idea that this war was all a hoax; just look at the color images! "Everyone knows they didn't have color film cameras back then! But here is the movie!!!"
"'
They've' kept this a secret for over 100 years!!"
Here's
a link to an Atlantic review that has some sample vid.
