I'm not so sure, I remember being unable to sleep after watching 'The Mummy' in my early teens because I found the idea of scarabs crawling under my skin particularly horrific, but haven't really noticed an effect since. I imagine horror movies may actually be better than more cheerful movies because they tend to involve dark scenes that probably don't mess with melatonin production as much. I would like to see that study happen, I think the outcome might surprise (especially if they compare several different genres).
