Revealing: When the Remagen bridge is bombed, it is obvious that the bomber planes shown have been taken from several shots (possibly also from an earlier film) and the shots were superimposed. Also, the bombers appear transparent, and the background sky's color is unnaturally strong, too.

Other: When Hartman's men raid the farm, they are fired at by one (and I mean, one) Panzerfaust gunner. The shots come in a much too rapid succession for just one single gunner using a one-shot anti-tank weapon, even with a quick assistant.
