To say I wasn't expecting much from The Tunnel is an understatement. After all, the film used to be available to download completely free via BitTorrent, with the full support of its creators. This documentary styled "found footage" film tells the story of a news crew that illegally gain access to abandoned train tunnels beneath Sydney in an attempt to uncover answers to a mysterious government cover-up.
The acting is surprisingly solid. There were times I got lost in the movie, forgetting that what I was watching wasn't real, which is always a good sign. The cinematography and sound are both outstanding and manipulated to build tension incredibly well. One minor flaw I noticed though, was that the film shows interviews with the two survivors from the very beginning. It becomes clear early on who is going to live and who is going to die. I found myself wondering how the other two characters were going to die far too early in the film.
Nevertheless, The Tunnel is a brilliant low budget horror film. Watch it with that in mind and you'll be pleasantly surprised.
