A pre-history of 'reality' horror film

With the rising popularity of 'reality' based horror films such as Cloverfield (Matt Reeves, 2008), Paranormal Activity (Oren Peli, 2007) and their sequels, it is fruitful to reflect on the history of such movies. While the international phenomenon of The Blair Witch Project (Daniel Myrick and Eduardo Sanchez, 1999) significantly marks the beginning of this newest cycle of 'reality' based horror film, its origins are fascinating and diverse. As far back as Michael Powell's Peeping Tom (1960), the lines between real and represented death and bodily trauma were explored.
