Brilliant psychological thriller, I dare to say Horror movie. After seeing this film you may need to sleep with light on. Unique screenplay, wonderful acting.

This movie actually reminds me a bit of a short movie a friend of mine made. It's called "Martha", a Belgian movie. Well at least it has some similarities. But Mientras Duermes (or Sleep Tight) is certainly a must see if you like psychological thrillers. There are a couple scenes where you can literally feel the tension. Luis Tosar plays his role as the mentally disturbed Cesar beautifully. It's an interesting story in the mind of a psychopath. There are not really gory scenes or so but the tension and suspense make this movie a little bit of a horror movie. Just for the story alone, if you imagine that there are disturbed people like that in this world. Cesar could be anyone, it could be someone you know, and that makes it frightening. I really enjoyed this movie from the first second till the last. It's a movie I'm keeping and that I will watch again in the future.

Sleep Tight is a lean and tight thriller. Not a horror movie in the strictest sense, more Hithcockian in execution. It's really Rear Window meets Psycho but without the follow-through. Cesar sneaks into people's apartments at night, since he's the concierge and has the keys for every one of them, and does stuff to mess with them and interfere with their lives. The film seems to ask questions about what a protagonist is in a story told this way, but I'm not sure it ever becomes more than superficial. The tension and the audience relation with Cesar when he's trapped in a woman's apartment would seem to indicate we are on the wrong side (what does that mean? do we actually feel bad for Cesar?).

Directed by Jaume Balagueró (Fragile, Rec 1, 2 n 4). The movie is full of tension and claustrophobic with a wonderful finale. It is not the easiest watch at times. The tension is high and the music score by Lucas Vidal (The raven, Fast n the furious 6, The quiet ones) follows the plot nicely. The first scene n the finale fits perfectly like a jigsaw. Very good twist. Non predictable movie. Good acting by the lead actor with perfect direction n awesome screenplay. At times, as a viewer, I felt as if I was also residing in the same building. Such was the impact of the screenplay n acting. Nice screenplay by Alberto Marini. The movie is a dark psychological thriller. The lead actor Luis Tosar (Cell 211, Miami vice, A night in old Mexico) is as odd and scary as Anthony Perkins was in Psycho.
