Factual error: The invasion was supposed to be at Dymchurch, as mentioned in the Blue Ray director's cut version. In the film, the invasion area is a sandy beach flanked by cliffs. In reality Dymchurch is a pebble beach and is on the edge of the Romney Marsh with no cliffs. The lack of cliffs can be checked via OS Maps of the area.
