The Holecheck Brothers directed this funny mockumentary of the 300, about what happened to the goat path that led to the downfall of the Spartan army:
It is known to any, the Spartan 300 army. Soldiers thought that death in the battlefield is the greatest glory they can achieve in their lives. But this is not that story, this is a story of a goat gate. And the five brave souls who were chosen to defend it. The 305.
