Continuity mistake: The Sandy/demon scene. When the cops arrive an officer says they had a report of 'someone at this address firing a shotgun'. But Harold who made the call to the police regarding his neighbour reported a 'suicide' attempt.

Visible crew/equipment: In the Sandy/demon scene, when the cops arrive an officer says, 'I know you, right? You're Roger...' you can see the boom mic reflected on the visor of his police cap.

Continuity mistake: The Sandy/demon scene. When Roger escorts the cops to the front door, he says 'My gun' and we see the cupboard door under the stairs (containing Sandy's body) is ajar. But when he closes the front door behind the cops the next shot shows the cupboard now closed.

Trivia: After the cops leave Roger's house, Roger is fighting with the sandy/demon upstairs then opens the bathroom door to release the floating garden tools. There's a 1958 poster of the movie 'The Blob' at the top left of the wall - another classic horror movie.

Continuity mistake: When the Sandy/demon tries the blow Rogers brains out he opens the bathroom door containing the 'floating garden tools'. The hedge cutter shoots towards Sandy/demon lopping off her head. Next scene Roger picks up the head placing it in a bin bag, but there's no blood, but there was when he shotgunned a hole in her from an earlier scene.

Continuity mistake: When Roger digs a hole in his backyard to bury the decapitated body of Sandy/demon he's startled by a neighbour who steps out of his swimming pool. Note the inconsistency of the sweat patch size on his t-shirt throughout this whole scene.

Continuity mistake: When Roger babysits Robert, the neighbour's son, he begins to cry, so Roger sits with him and watches TV. All of a sudden the tears on the childs face miraculously dry up between cuts.

Revealing mistake: Later into the film Roger realises that his aunt's paintings hold some significance to the whereabouts of his missing son. He removes a cloth from the top left of a painting revealing an image of his son trapped in his bathroom cabinet. Note the cabinet door is the wrong way round to the one in his bathroom.

Continuity mistake: In the scene where Sandy visits Roger's house, the 'cross' on her necklace changes position and back throughout the scene.

Continuity mistake: When Roger returns from leaving his partner Ben who is captured by the Vietnam enemy, note the position in which Harold is holding the stoker object in his right hand whilst propped on the mattress, it moves from his stomach to his upper chest between cuts.

Continuity mistake: When Rogers blasts the Sandy/demon out through the front doors we see a supposedly large bloody hole in her back, but no blood nor damage to the doors.

Paul Andrews

Continuity mistake: When Sandy turns into the demon she's still wearing her own clothes, however her footwear has gone from high-heels to blue socks and white leg warmers. Most noticeable when she gets shotgunned out through the front doors of the house. Then she reverts back to human and is wearing high-heels again.

Continuity mistake: After the cops leave Roger's house, Roger is fighting with the Sandy/demon upstairs, note how the large shotgun hole in her body has suddenly disappeared.
