Even when depicted as foreigners (including aliens from outer space) all actors speak and understand a common language (usually English) unless the film's plot depends on a language barrier.
When foreigners appear in movies (hispanics in particular) they seem to be able to speak perfect english without making one single mistake except it seems they NEVER manage to learn how to say "Sir" or "Thank you"... they always say "Senor" and "Gracias".
