Continuity mistake: The day Kristin is admitted into the hospital, she is screaming and fighting with the staff. She then cuts Max on his right inner arm with a scalpel. In the next scene where Max is introducing the kids to Nancy, Max has a very small band-aid where Kristin cut him yet the band-aid is on the outer part of his arm by his elbow.
Continuity mistake: When Nancy is talking to Max about seeing the kids one last time, the front shots show her standing straight up. But the shots from behind she her leaning against the wall. (01:04:10)
Continuity mistake: When Jennifer's head goes into the TV, the antennas on top are gone just after Freddie's arms come out of the TV, but in the next shot they are back.
Factual error: This film begins with a foreboding quote attributed to Edgar Allen Poe: "Sleep. Those little slices of death. How I loathe them." Problem is, Poe never wrote any such thing (and neither did Henry Wadsworth Longfellow), despite decades of misquotes and misattributions across the Internet. So, where did the quote actually originate? The answer is Walter Reisch, lead screenwriter on the 1959 film "Journey to the Center of the Earth." In Reisch's screenplay, the antagonist Count Arne Saknussemm is urged to get some rest, to which he memorably replies, "I don't sleep. I hate those little slices of death."
