What language did Pilate speak?

Just that this film doesn't purport to be historically accurate.

Wasn't the Lingua Franca of Palestine/Israel/Judea/Outremer/Whatever Aramaic at the time?

one thing to note though is that the latin used in the movie uses the ecclesiastical pronunciation (with italian accent). The way old latin sounded is estimated by scholars, we can have some hints but it's hard to know how exactly it sounded.

Well, in the 1st century AD Judea it certainly didn't sound at all.

I had completely forgotten about Aramaic, you're right user.

Aramaic was only spoken in the Levant, but Greek across the whole Eastern Med.

My guess would be a language the crowd would understand, so probably Greek or Aramaic. People can learn more than two languages, and for an official in his role it would be expected to know the language the people can understand.

Scripture doesn't say what language he spoke. There is no reason not to think he spoke Latin to the crowd. It doesn't say otherwise.

Honestly it never occurred to me why he would have used Latin, but thinking about it, would make sense to use Latin if he is pronouncing a sentence.

It would have. Roman soldiers would have spoken sermo vulgaris (or perhaps in their case the sermo militaris), and since it was the language of command, Roman officers would have used it too.

Why are you so paranoid? There are probably many other minor historical inaccuracies into that movie. This is an interesting topic, interdenominational shitflinging is completely unnecessary on this topic.

Polite sage, as my comment doesn't address the point of the thread.
