From the photo on the linked story, the Roman legionaires were apparently Greek hoplites too stupid to put their helmets on. LOL

The Romans almost always fought in open order. The gladius was not intended to be used above the shield, but rather to its side. It was normally used to thrust either straight forwards or in an upwards direction.

Very true, but apparently not dramatic enough for cinematography.

There was a trilogy, "The Centurions" by Damion Hunter which was absolutely fascinating. The Roman Army was years ahead and quite remarkable.

I believe that everyone understands that soldiers of legions wouldn't hold their swords above the shields, but the demands of Hollywood......
