This screening takes place on the third night of Fright Fest 2014, the UK's premiere international fantasy and horror film festival. You can find the details of the festival here. I am indebted to horror film expert Nigel Floyd for his suggestions and selections.
Here is the Fright Fest introduction: Repulsion meets 'The Gruffalo' in writer/director Jennifer Kent's Sundance acclaimed debut feature as the unresolved traumas of a conflicted mother and disturbed son manifest as a malevolent entity threatening to consume them both. Amelia (Essie Davis) and her son, Sam (Daniel Henshall), have had a raw deal in life. Her husband Oskar died six years prior while driving her to the hospital pregnant with Sam, and his birthday is a particularly painful reminder. But now things worsen dramatically. Samuel's been having nightmares, and when a mysterious pop-up children's book appears on his shelf titled 'Mister Babadook', he is finally able to put a name to the terror.
Here (and above) is the trailer.
