Research and Planning - Location of trailer

So me and my partner decided that we'd like to film the trailer within the backstreets of town, where it's desolate and quiet, plus it's quite spookey there due to all the allies and sub-urban atmosphere and buildings. It's like a 28-day later location, but not following the same story line etc, we just like the idea of a huge city being completely wiped out, and our main character being the only surviver of a huge break-out.  We'd most likely do this in Manchester, as it's conveniant to where we're located and we understand the area of the town.

 

The allies will look similar to this, as these backstreets are located somewhere around Manchester themselves, however...our trailer won't be located particularly here, we may vary around the town to find suitable areas.

Other areas that could be suited for an action/horror movie could be somewhere like in a different country like within Laura Croft or Underworld - different locations spreaded around the place and not just fixated on a town etc..  Obviously we don't have budgets for our trailer, so we cannot build new parts of scenes that would join together to make a perfect location.

If the movie wasn't so action and more horror, it could take place in a little village, not a town.  This would be more difficult for us to film however as we'd have to require permission off the public so that we could film around their residential area - Some may say no.  We'd also have to find a suitable house that we could film in for tiny snippits of the movie, if neccessary.
