The story is pretty close with both films, which did surprise me a little bit. Two things really set the two movies apart though. One is the main character. Marvin is just a guy looking to be on his own. In the remake he is an ex con. The other noticable difference is that Sigaw spends more time telling the story of the family that is haunting the place. I wouldn’t call it a lot more time, but it does show what happens behind the closed door more than the remake did. It also tells the story of Jude (James Blanco), who did try and help Anna and Lara a little bit at least. I found this story a little confusing at first since I didn’t notice right away that it was a different guy from Marvin, even though the apartment was the same. This did help explain some of the things that Marvin was seeing and hearing though. Those things went unexplained in the remake though. Since Marvin is at the apartment as much as the main character is in the remake, it does makes sense that they fill the time with backstory.
