TONE
At the beginning of the film, the lighting is warm, bright, and adventurous, lulling the audience into a false sense that this is a traditional romance. Amelie's world is blue-sky days and joyous colours. Oskar's is dark shadows: grey and black. Just opening suitcases next to each other on a bed illustrates the point.
And when they come together, it's the aurora borealis in all its majesty. The reflection of fairy lights on a lake. It's city skylines and the rustle of emerald trees in a forest. It's whisky and wine inside crystal glasses. First class seats and A-list treatment. It's the cover of night for erotic play.
As the film progresses and the threat of danger is revealed, the lighting and colours become darker and ominous. We understand there is a gulf between our heroes that may be too great to overcome.
