Jeruzalem is a Found Footage film. However, it takes the unique perspective of being filmed from the perspective of a girl (Danielle Jadelyn) wearing a pair of internet accessible glasses. (You presume these are Google Glass, although this is never specified and the technology present is so advanced to nominally classify the film as science-fiction). This places Jeruzalem into the same vein as a bunch of recent films such as The Den (2013), Open Windows (2014) and Unfriended (2014) in which the computer screen becomes the film screen as we see it constantly interrupted by a plethora of video windows, chat sessions, drop-down menus, information searches and text messages.
Jeruzalem works fairly well even in a field that is becoming as tiresome and played out as Found Footage genre. With its labyrinth of enclosed streets and multi-cultural mix, Jerusalem makes for a fantastic location. Even the Israeli actors cast as Americans come across as reasonably convincing. The Paz Brothers absorb you in the journey of the two girls and take their time before allowing the horror element to erupt. Thereafter the film delivers a solid and satisfying run through.
The only frustration of the film is that you spend much of the running time trying to work out what the threat is it seems to be trying to be a possession, a fallen angel and a zombie film all at once. The various explanations we get from Yon Tumarkins Kevin give the idea of it being something that lies at the core of all world religions that emerges at Yom Kippur. What we see looks like zombies/possessed figures with wings, which are seen circling around the city in flight in a couple of scenes. Although in practice, the Paz Brothers never do too much more than cycle through a bunch of zombie and possession/infection cliches without alighting on any one explanation in particular.
The Paz Brothers have announced a sequel Jeruzalem 2.
