Other mistake: The woman who checked into the Mercer hotel said she thought the reservation was under "Perratti." Bart initially gave her Room 109, but switched to Room 124 - where he had hidden cameras - saying the room was nicer and had French doors that gave access to the pool area. The woman's husband, expecting to meet his mistress, went to the French doors and knocked to get inside. He should have gone to the room that was initially assigned because he could not have known Bart switched to Room 124. (00:08:52 - 00:10:05)
Character mistake: Bart is sitting on a bench outside the hotel. After Detective Espada talks to the Mercer hotel manager/owner, he goes to talk to Bart. Bart has blood on both hands and lower left sleeve. Detective Espada is supposed to be investigating a fresh murder case that puts Bart at the scene, but he does not confiscate Bart's bloody clothes, conduct a gun powder test on Bart's hands to check for residue, or take him to the police station for formal questioning. Espada did not follow police protocol. (00:17:36)
Continuity mistake: The replay of Bart and Andrea's conversation at check-in are not verbatim - at times, only a word or two ("uh", "um", "just") is added, but other times there are parts that simply were not stated. Granted, Bart is practising and his additions are not meant to be a reflection of what was actually stated, but the things Andrea said were on tape and these do not always match. Bart did not ask, "Seven nights?" and Andrea didn't reply, "Yeah. A week, maybe longer. I'm not sure yet. So, you're new." (00:27:14 - 00:28:47)
Character mistake: Several police officers are outside the hotel looking for evidence. Inside the room where the murder occurred, other officers/detectives are looking around. None of them are wearing gloves or shoe covers. The hotel manager is the one who found the camera card - even though Det Espada should not have allowed him in the room during the investigation and police should have found it the first day. Det Espada handles the camera card without wearing gloves. Det Espada did not secure the crime scene. (00:35:50)
Audio problem: When Bart is looking through a magazine and starts to rip a page out, the whole page is lifted and obviously already loose; Bart sets it down to look like he is tearing it out, and sound effects are added to make it appear he really is ripping out the page, but the sounds don't really match his motions.
