Dirty Harry - S4-E5
Other mistake: When Lundy is shot and falls to the ground, there is no visible injury even though he is facing the camera. Later, Masuka says he was shot twice, once in the chest and once in the neck. The shooter was facing him. We should have seen the blood.
Factual error: In the newspaper article from the Trinity killers past - the report states that someone called 911 and dispatch gave them instructions. The death occurred in 1959. The first 911 call was made in 1968. (00:39:24)
Character mistake: In this episode, as well as 1-2 others, Dexter holds his slide phone upside down (only in the edits/cuts where he wasn't shown answering the phone). When the phone is slid open, the front cover goes above/higher than the backside of the phone. And a few instances I've seen, the side closest to his face 'lower' than the outside/backside of the slide phone, strongly suggesting the phone was held upside down.
Slack Tide - S4-E7
Other mistake: When Dexter shreds Laura Moser's file, he actually shreds a file for Estrella Carazo. (00:32:57)
Continuity mistake: Arthur and Dexter make a u-turn to avoid a DNA checkpoint. The view from outside the van shows no oncoming traffic, but the view from inside the van shows several cars waiting for them to complete the u-turn. (00:53:20)
Continuity mistake: When Dexter is packing kill tools for the road he "packs light" and chooses a knife and hammer. However once he's at the hotel room setting up the kill room he unrolls his entire set of tools like he does at all the other murder room scenes.
Other mistake: There's no way Arthur could have known Scott was 10 years old. In fact, it's highly likely he would not have known any of the boys he killed were 10 years old.
Continuity mistake: When Dexter is killing Stan Beaudry, the drop of Beaudry's blood encompasses the width of the blood slide when the two pieces of the slide are pressed together, but then goes to being roughly half the size when the shot changes.
The Getaway - S4-E12
Other mistake: The tub Rita was found in was full of water, to the rim. Volume displacement dictates that when Arthur got out of the tub the water level would have dropped to well below the tub's rim.
Continuity mistake: Deb moves in with Dexter to his apartment in a 2nd bedroom during season 2 following the ice killer's kidnapping and attempt on her life. But in Season 5 when they try to share this apartment again, it's only 1 bedroom now?
Continuity mistake: When Lumen stabs Dexter with his knife in the swamp, she hits right above his elbow which he grabs promptly. When the camera angle changes, he's now grabbing his upper arm that's bleeding from a different spot than where he was stabbed.
Everything Is Illuminated - S5-E6
Continuity mistake: Lumen has a dark "H" shaped scratch on her right shoulder. A few minutes later, its turned 90°, like a sideways "H," and it is very faint. (00:22:05 - 00:32:35)
Character mistake: Searching for clues to identify a suspect, Masuka takes fingerprints from the interior of a truck. Back at the lab, he says he had two dozen prints and they all belong to the same person. Unless the prints are all of the same FINGER, there is no way he could know the prints were all from the same person without a suspect to compare them to. Masuka is a forensic expert and should know better. (00:15:40)
Other mistake: Lumen agrees to meet her former fiancé Owen at noon. When they meet up, the sun setting in the background indicates that it's evening. (00:16:12 - 00:23:39)
Factual error: When Dexter is punching Olivia's father in his left side, he says "That's your liver." Only the liver is on the right side. For a serial killer who routinely dismembers bodies, Dexter should know which side the liver is on. (00:42:50)
Revealing mistake: When Dexter stomps on Barry's kidney, you can see his foot doesn't even make contact with Barry's body.
Revealing mistake: When Dexter is fighting Liddy, in the van after kidnapping Dexter, the knife is a rubber fake knife. (00:38:15)
The Big One - S5-E12
Continuity mistake: When Dex gets the phone-call from the city archives he steals a red Pontiac Grand Am GT. When he crashes it at the camp it's a badly-painted orange Chevrolet. (00:21:00 - 00:28:00)
Suggested correction: The car is a red Pontiac but it is a Grand Prix, not a Grand Am.
Continuity mistake: Dexter's hybrid SUV changes often. Sometimes it has satnav, sometimes it doesn't.
Revealing mistake: The actor portraying a dead body noticeably moves her left leg while being turned over by Angel, Dexter and Masuko. (00:06:33)
