Thanks go to snikt73 for the scoop!
I was a part of the WWII, Omaha Beach scenes (photos of this have hit the net, so no spoilers there). From what I can gather, Logan (aka Wolverine) is pretty much the Eternal Soldier archetype. By this I mean he is by nature a warrior and is drawn to wars and conflict. The D-Day landings at Omaha Beach are iconic in American military history. It makes perfect sense from the character story to have this landing as a setting for some of his history.
About 70 extras were hired on for the shooting of the beach landing scenes (plus stunt guys plus stars). These extras were a mix of normal extras and trained army personnel. I fall into the latter category being a member of the Australian Army Reserve. The casting directors wanted to leaven the bread of actors with some real-life soldiers in order to give the scenes a little bit of added realism. I think it worked well.
On day one of the shoot the army blokes were given command of small units of the WWII soldiers. They were given ranks - corporals, sergeants and one officer. Their role in the landings was to lead their troops up the beach. As every Australian soldier is trained in this sort of small-team leadership, this proved to be no problem. All of us were thrilled at having been given rank for the shoot.
Morale was high on the set. Every single extra was there for the love and fun of it. Sure, I doubt people would have done it for free, but no-one was there just because of the money. The chance to play soldiers alongside one of the coolest comic-book characters ever created? Every single one of us out there was willing to give it 100%. And we did.
The week before we'd all been gathered and trained in the weapons & assault techniques of the time - those of us who had trained in modern techniques had to forget what we knew and start again. The weapons we were using were the real deal WWII issue weapons and so safety was a priority. We had to learn how to fire and handle these weapons just like the real soldiers. After our training, we all had bruises and bumps, but we felt good about knowing what we had to do.
The filming was done up near Newcastle to the north of Sydney, Australia. We filmed from sunrise to sunset. The days were long and cold. Such is life. All of us extras kept in our mind the guys who wore these uniforms some 60 years ago in Normandy - if they could do it, so would we. None of us wanted to disgrace the uniforms we wore.
We wore the uniforms of the 29th Infantry Division. The 29th landed at Omaha and fought their way across Europe to push back the Nazi war machine. They were heroes. Which part of the 29th were we? Well we landed at Omaha under heavy fire, so that makes us the 116th regiment, I would have thought. We weren't the first off the boat, but we were still in the first wave. If you're a history nut, some of the details might be a little sketchy, but these things happen in the movies. A good estimate, if you really want to know, is that we were C Company of the 116th regiment of the 29th Infantry Division. We charged off the boats, quite a few of us fell under the guns and the bombs, and the rest of us - led by Logan and a few others - fought their way up to the cliffs and the German bunkers. Back in 1944 that's pretty much how it happened, so that's good enough for me.
The beach scenes were a lot of fun to do. We all got covered in sand, soaked through from the surf, choked on smoke and were buffeted and deafened from explosions. We charged up that beach so many times we all sweated half our body-weight. But every time we lined up to go again, we gritted down and gave it our best. It was fun. And we wanted to do as good a job as we could.
Hugh Jackman and Liev Schreiber, it must be said, seem like really great blokes. I know everyone says that about the stars, but it is true about these guys. When the set was being dressed with all the explosives, Hugh went and signed autographs and spoke to the crowd that had waited so patiently to see him. When he could, Hugh swung by and gave a few words of encouragement to the 70-odd extras. Liev, obviously not as big a star in Australia as Hugh but still a name-to-conjure-with, had something of a sly smirk on his face most of the time and seemed to be genuinely enjoying himself on the set. Liev & Hugh ate alongside the rest of us and both of the guys got wet and covered in sand & explosive debris just like the rest of us. (Every time an explosion went off near them the sand would stick to the make-up on their face! I recall coming out of one take and with another extra and the four of us - Hugh, Liev, the other extra and myself - were all looking at each other and grinning as we spat sand out of our mouths and blinked it out of our eyes.)
It's an odd thing about Australians as a people. We're generally not seen as respectful polite folk. We're loud and brash and arrogantly friendly. Yet no-one from us plebians amongst the crew bothered the stars. We all figured, "well, I guess they're busy so we'll just leave them to it." Sure, we all know they're normal blokes and when the opportunity arose - lunch queues, costuming, and other casual encounters - we all spoke and joked with each the stars just as they did with each other. But for the majority of the time, no-one bothered these guys and left them to get on with their job. This attitude could be seen with the crowd on the beach too. They waited patiently. They didn't yell or cheer or carry on. When asked not to take photos with long range cameras, they agreed. (Well most did, Australians have never been too good at obeying regulations!) When asked to move out of shot, they did so without protest. A couple of school groups came down to watch and got impromptu lessons from their teachers about movie-making and the Normandy landings. (We extras were thrilled at one point to see a group a children imitating our charges up the beach!) In short, it was all very civilized and pleasant.
For the final scene of the shoot the special effect guys went all out - and didn't tell us what they were doing. We figured it was just another charge up the beach. We had picked our spots to dive, take cover and die according to the lie of the land. On the call of "action" we set off and the world went to hell! The effects guys had basically rigged the entire beach to simulate mortar explosions and machine-gun fire - and to a much greater degree than ever before. Sand and smoke and noise obscured everyone's view. No-one could see and hear a thing. People dropped and took cover, on instinct as much as on training. Time slowed. (Everyone said this afterwards - when the explosions went off, everything moved into slow-motion. Not that it mattered. People were still confused and disorientated, and no-one could see or hear a thing beyond a few feet.) I recalled the words of one of the lieutenants from the Omaha Beach landings: "there are two types of people staying on this beach - dead guys and guys who are going to die." I couldn't see a damned thing - I had sand in my eyes and my ears were ringing - but I was supposed to be leading. I had a job to do. I charged forward anyway, hoping I wouldn't run head-first into one of the barricade that were scattered across the beach. As I went forward I found blokes on their guts, taking cover from the explosions. I grabbed them and screamed at them to get moving up the beach. I even kicked a few. I took what shots I could with my M1 rifle, but mainly I just kept moving and pushing the blokes along up the beach and away from the killing zone. When they moved they just did as they had trained to do - took a few steps, took cover, fired if they could and them moved again. When the director yelled CUT we all just kind of stumbled around and tried to blink the sand and smoke from our eyes.
We were told later that the look of confusion and disorientation in soldiers who, while shot all to hell, ADVANCE
