If you loved Emisario de otro mundo, try El hombre con ojos de rayos X
Un puente entre una película que ya has visto y una que casi nadie ha cruzado. Esto es lo que comparten, y lo que la segunda hace que la primera no hace.
Lo que comparten
Both films are directed by Roger Corman, and they both carry the paranoid mood tag, and they sit in Horror / Science Fiction territory. If that's the register that drew you to Emisario de otro mundo, the second film will land in a comparable space — through a different lens.
paranoid
What El hombre con ojos de rayos X is
Rooftop. Midnight. A pigeon's coo. A scientist's self-experiment grants him vision beyond sight, a gift that quickly warps his world and endangers everyone around him. Corman's sci-fi paranoia plays on primal fears.
