Gallipoli (1981)

Factual error: Mel Gibson and Mark Lee leave their jobs working on the Pichi Richi Railway (north of Adelaide) to join the Australian Light Horse Brigade (about to sail to Turkey from Perth in 1914). To do this, we see them travel over 1000 miles across the Nullarbor Plain by train. But the tracks were not laid until 1927.

Army Doctor: Teeth aren't all that good.
Snowy: Supposed to shoot the enemy mate, not bite them.

Trivia: Australian playwright David Williamson makes a cameo as the tall player in the opposing team in the football match held near the Pyramids in Egypt.
