The logo for "Canon Pictures" seen briefly at the start is an homage to "Cannon Films", an independent production studio known for their cult genre movies during the 1980's.
The scent of an air freshener tree in Becky's closet reads "Normal".
The bedside clock changes in real time as it's seen throughout the film, beginning at 11:56, then 2 minutes later 11:58, and 1 minute later 11:59. Based on this progression, the climax of the film takes place at midnight. After Rick faints there is an unknown passage of time, but in the final shot, the clock can be seen briefly and reads 2:37 - a reference to the haunted room in The Shining (1980).
The nightstand books are titled "How To Get A head" and "Trash Trash Trash".
