Research and Planning - Trailer so Far

We have not finished filming our trailer as the editing has not finished , the editing is only been done up to a minute which is the build up, we have been planning ways to make the trailer come across more as a horror/ thriller as we were told the genre isn't very clear. We had some more footage which we had, but unfortunately the memory card has been taken out of the camera we have used, we spent lunch time trying to find it, but we didn't find it, so we will need to film these scenes again ASAP.
