Having toured Normandy, St. Mere Eglise, Aromanches, Bayeux, Caen and several other sites, I have to say that this movie is about as accurate as you can get, especially the part about the bridge over the Orne River, the Pegasus Bridge. Also, the scene where PFC John Steele is hanging from the steeple of the church at St. Mere Eglise conforms to the real scene right to the "t."
You have to go to Normandy and see the Longe batteries, St. Mere Eglise, Pegasus Bridge etc..., then see the movie and you will walk away with nothing but appreciation for what was done by the "Greatest Generation." I wish I had been a part of it.
A movie of this type, coupled with actually seeing the real sites makes you proud to be an American.
