Maybe for the same reasons that modern media depict fighting styles that don't exist, e.g. more suitable for the medium, more easily depicted, greater aesthetic potential, political/ideological propaganda purposes, or just good old-fashioned ignorance.

Depictions of hoplites using spears overarm may be entirely accurate...alterntively they might rank alongside guns with limitless ammo, faster-than-the-eye kung-fu moves, jet-packs, and all the other movieland fictionalised combat clichés.
