How the critics gave this one a 6.9 on IMDB is a mystery to me. Six years after George Romero's groundbreaking "Night of the Living Dead," we have an Italian zombie flick that already feel formulaic and predictable. This one did nothing for me. The story centers on a couple who become the targets of a zombie attack that was caused by the use of radiation on local farms. Ugh! How 1950's.
Unlike other Italian films that bring us interesting zombies [Zombi 2, for instance] the ones in Let Sleeping Corpses Lie [LSCL] are actually boring. Yes, they shamble around like proper Romero zombies. But they don't inspire the feeling of fear and dread that Romero's do. For those who care, there is blood but it's not the kind that makes you really squirm in your seat.
LSCL has both Italian and English actors and the American version of the film is dubbed for both. This is always a little weird because the English track doesn't always line up. But after a while the viewer stops paying attention to this so it's not too distracting.
The cinematography and direction are fine on this but LSCL feels like a poor version of Night of the Living Dead. Too bad director Jorge Grau didn't study Romero's film more closely. He could have learned a lot about how to make an iconic horror flick that is still creepy over forty years later.
