 FACT: The sailors put into port on what is supposed to be a small  island off the West coast of Ireland. They encounter a local, and  ask him a question, which he answers in Irish (Gaelic): "Cad a  dhéanfaimid anois?" while gesturing in the direction they need to  travel. This means, "What will we do now?" Anybody who understood  this will wonder why he would answer in this way, until later in the  film, when it gradually emerges that this is what he always says  when required to utter a line that we are not supposed to  understand. There is actually one occasion when the phrase used fits  the situation.
