Death Tunnel Trailer

Death Tunnel is a horror film showing the Haunting of Waverly Hills Sanatorium in Louisville, Kentucky. This horrific five story structure is listed as one of the Top Ten Scariest Places on Earth, due to the 63,000+ deaths. The film shows 5 young girls enduring a 'college initiation' where dared to spend the night seperately on the 5 floors of the haunted sanatorium. I particularly like this film trailer as it is believable. I find the opening of the trailer extrememly effective with the camera focusing on the wheels of the trolley and the quiet whispering followed by a chilling scream and loud bang with the caption 'based on true events' with an establishing shot of the sanatorium. The trailer particularly focuses on the 5 girls seperated on the 5 haunted floors and this is shown by extreme close ups and flashes of the terror that they endure.
I find this trailer very useful as it will help my partner and I to see what really makes a horror film trailer terrifying.
