Director B.C. Furtney’s horror thriller watches almost like an off off-Broadway play somewhere in some run down theater. “Do Not Disturb” watches like it began life as a stage play and then was turned in to a screenplay after it languished for a few years. Filled with horror genre notables, “Do Not Disturb” is mostly confined to the setting of one room, and is about as dull as any self-important stage play you’ve seen in Manhattan. It’s great to see Stephen Geoffreys in a lead role again, but his performance is lackluster, comprised of dull lines with a performance that seems apathetic. I’m not sure if the character Geoffreys is playing is a bore, or if Geoffreys himself is just bored with this role, but “Do Not Disturb” covers no new ground, genre wise. Geoffreys is tortured writer Don Malek who is a shut in reserved to his room. He’s captured and began torturing his former Hollywood agent, and his book agent Ava is wondering when his next book is in. Unknown to her, Don has begun inflicting a plan of revenge against the people that spurned him. And soon enough, Ava catches on and wants in on the fun. Furtney doesn’t have a lot to go on with the material he presents here, offering a prologue that’s pretty much the entire movie in a nutshell. The hour after the first twenty minutes feel like filler and endless exposition that goes nowhere. Geoffreys doesn’t really take the role by the balls, so co-star Tiffany Shepis has to pick up the slack. As his passionate book agent, she screams and barks at Don about his lack of writing. And Geoffreys mostly recites his dialogue in monotone yawn inducing delivery that fail to sell his immense insanity and vengeful mindset. Don really does nothing but sit in his room, kills a neighbor who was violent to a prostitute, and then sits around some more discussing his plans for revenge. Shepis has half of the screen time as the book agent losing her clients to a quick talking new agent in town, and she turns to Don in hopes of squeezing a new book out of him to put them on the map. But Don is much too concerned with revenge to write anything. I think the lack of a computer or notebook should have tipped someone off, eventually. “Do Not Disturb” is an unremarkable tedious genre entry that offers no new insight in to the concepts of revenge, writing, or the darker corners of the writers mind. In the end, it’s a test in patience, even for folks clamoring to see Geoffreys in a new horror outing.
