found this museum example of a later persian shield:

edited: just watched some clips from that movie. the legionaries in the film were indeed equipped with this shield, which appears to be of metal with an arm loop and hand grip, a type never used by roman troops. they all used centre hand grip shields. this style is a much later style favoured of mounted troops. the symbol is the movie distortion of the common winged scutum symbol as shown in the post above. i agree the symbol is based on that, but the whole gestalt is wrong. as noted in the post below, the romans used laminated wood shields, flat or curved with a central metal plate or boss to protect the hand. as noted only one has been found which shows the laminated wood strip constuction. they are amply illustrated in stone on roman monuments like hadrians column.
