Rammbock: Berlin Undead Movie
This film is only 1-hour long, and it showcases "false zombies" -in the sense that they are just like the fast ghouls from 28 Days Later. But don't let this deter you from watching it. It, like Horde, as a foreign zombie film, is quite good and above most of the American low-budget zombie efforts. It's principle is almost identical to that of REC or Quarantine, and in many ways, it could almost be an exact sequel to those films, just set in a different region - in this case Germany.
What does separate it, is a very sublime humor (though it's not a comedy) and the fact that there are several new ideas introduced to this zombie breed. Two, being a way to partially suppress the infection via sedatives, the other is the extreme photosensitive eyes of the ghouls -to which is taken advantage of by using camera flashes to repel them back a bit.
This is quite an entertaining film with more than decent acting, although it's subtitled, as the original language is in German, I still recommend it, especially if you liked Rec, Quarantine, and 28 Days Later.
