　　Stine and Teit, your average urban middle-class artists and intellectuals, leave Copenhagen for the wilds of neighbouring Sweden’s forest. Soon, they find out that something is strange there – most disturbingly – when their son Nemo suddenly thinks his mother isn’t really his mother anymore. It becomes clear once Stine and Teit discover that they have neighbours who look exactly like them –(🍐) mirror images made flesh and blood.
　　The subject of reflections and doubles is introduced in the film’(🗄)s first shot: a view of a lake landscape turned 90°(➗) so that the water’s surface runs vertically through the image’s centre. Only once the shot gets tilted is it revealed which side mirrors which. Later, a mother and child are reflected in a glass door.
　　However, this is not your doppelganger thriller of the gothic variety. Note the title: in physics, superposition means (per Merriam-Webster) "the combination of two distinct physical phenomena of the same type (such as spin or wavelength) so that they coexist as part of the same event". This is more a metaphysical meditation towards the realisation that none of us is ever alone, but also never unique.
