Aliens have not yet visited Earth, at least not officially. Nonetheless there are numerous scientists, diplomats, and military experts, equipped with advanced degrees and volumes of preparatory planning, ready to deal with such an event – should it ever happen. Danish director Michael Madsen trains his impeccably dry humour on these people, who (mostly) aren’t crazy. They recognise that an alien visit would have profound consequences for everyone on the planet and that having some kind of plan is better than having no plan at all. They gamely describe their thinking, don airtight suits to protect against hypothetical pathogens, and test out the first sentences of greeting in this fascinating, beautifully shot film.
