[1] It had its world premiere on 23 August 2014 at the London FrightFest Film Festival and stars Leila Mimmack as a call girl who finds herself entangled in a series of strange events surrounding a hidden room.

[5] Coming Soon gave a mixed review for The Sleeping Room, writing "While the leads are appealing and Fiskin is very creepy looking, the mystery fails to deliver suspense or scares.

And the conclusion, a dragged out chase and showdown in the old building, is perfunctory and fairly dull, making a short movie feel much longer than it actually is".

It wrote: "[John] Shackleton never knows whether to stick or twist leaving The Sleeping Room engaging the wrong gears like a premature learner driver behind the wheel for the first time".

[7] Jon Dickinson of Scream was disappointed with the lead role in the film, stating that "[John Shackleton] had a firm foundation to make his feature debut an incredibly creepy experience thanks to an interesting concept devised by [the screenwriters], but the end product is anything but".
