I've just finished watching the film Zulu, which got me thinking about other similar classic scenes in cinema history. Here are some of the ones I've seen:

1 The Alamo (Davie Crockett at the Alamo)


2 Hoth (The Empire Strikes Back)


3 Helm's Deep (The Two Towers)


4 Rorke's Drift (Zulu)


5 Thermopylae (300)


There are probably other candidates, but that's all I can think of at the moment.
