Guillermo Del Toro is the producer and Hitchcock the primary influence in this supercreepy Spanish horror.
Belé* Rueda plays an astronomist, Julia, who's going blind from a degenerative illness, the same one that induced her twin sister to kill herself. Or did she? Julia believes otherwise, and just as her sight fades she starts to uncover the disquieting possibility that her sister had a stalker. Writer-director Guillem Morales takes some standard tropes – dark corridors, power cuts, lurking silhouettes – and turns them to good advantage. It's about half an hour too long, but the play on blindness and sight is authentically sinister.
