There were almost as many British troops as American troops taking part - 62,000 British troops and 73,000 Yank troops.
11,000 more Yanks saving your butts... Meanwhile hundreds of thousands of Yanks are battling on the other side of the world carrying the fight to the Japanese.
YOU FAIL
The American landings on Omaha beach came the closest of all to failure, and the foothold gained there was much smaller than planned and the most tenuous of all the beaches. The Americans may have performed better there if they'd actually taken up the offer of British floating tanks rather than wanting to do things their own way.
It was also the most opposed. The Brits as always were given the easy mission while Canadians and Americans were given the tough mission.
And it was never close to failure... Omaha was taken and that was that.
So I'd say the British were the most effective of all during the Normandy Landings.
Least effective by far and it was a war that the Brits started.
And Saving Pvt. Ryan was a fictional movie about Americans finding another American in Normandy. Why should they have put Brits in the movie?
The Canadians, of course, failed to capture ALL of their final D-Day objectives on Juno Beach.
.
Canadians achieved all their objectives on D-Day but had to withdraw because the Brits didn't and their flank was in the air. This became common throughout the Normandy Campaign... Brits not achieving objectives and moving far to slow for hard charging North Americans.
You'll find a lot of films nowadays which are factually incorrect. The Americans, for example, are quite at making movies which credit Americans for doing something which, in real life, were committed by others (as already mentioned in the article, by watching The Great Escape you wouldn't think that no Americans actually took part in the real-life escape and that it was almost an entirely British piece of derring-do).
Its why they are called movies.
Take Transformers for example. In the beginning they show the British Beagle II Mars Rover starting to transmit from the surface of Mars and a Transformer crushes it.

When in fact Beagle II wasn't even a rover and the Brits smashed it into the surface of Mars due to their incompetence. The Brits couldn't even land a simple probe on Mars never mind a rover.
