Continuity mistake: At the end a shot is shown of the FBI airplane in mid air. The airplane shown is a Gulf Stream V; which has a very distinctive nose. After the scene inside the airplane; another shot is shown of the plane's exterior, however all of a sudden they fly a Gulf Stream 100, which is a significantly larger plane and a very different design. (00:41:05 - 00:45:00)
Revealing mistake: When showing the corpse's neck where the puncture marks are, you can see her pulse. (00:16:38)
Magnum Opus - S8-E13
Character mistake: Blake says the unsub must be a universal recipient blood type, AB pos, but they are talking about receiving plasma. The plasma universal recipient is O neg, the opposite of what it is for regular blood transfusions. (00:33:27)
Visible crew/equipment: After the three people at the restaurant patio are shot it cuts to the black screen, and in the next shot as the camera pans over the blood stained table, the red T-mark is visible on the ground in front of Gideon's feet. (00:13:15)
Perennials - S8-E11
Deliberate mistake: In the outside shot of the unsub's motel in Pensacola, Florida, the sky is black as if someone behind the scenes tried to digitally remove part of the background in post, but did a really bad job.
There's No Place Like Home - S7-E7
Character mistake: On Travis James' arrest report it shows his DOB as 10/28/98 and Garcia says he is 22. This show is based in 2011 at this point so the DOB should be 10/28/89.
Visible crew/equipment: A crewman's left hand (with wedding ring) on a black metal railing is visible on the left side of the shot of the woman at the corridor intersection. (00:24:57)
Visible crew/equipment: As Rossi comes to Morgan's rescue you can see a guy behind Agent Rossi seemingly holding a camera. A few seconds later Morgan gets up and right before he turns to punch the henchman guy you see the same camera guy again. (00:34:33)
The Fisher King: Part 1 - S1-E22
Visible crew/equipment: When Elle arrives back at her home the camera pans and you can see the face of a man in the mirror. A man who is not the Fischer King as he has no facial burn marks on him. Potentially simply a stand-in for the character or the actor without the makeup as when the Fischer King is going to shoot Elle you cannot see his face.
Visible crew/equipment: When the team enters the house of the unsub it is dark. You can see a second camera man twice off to the side who is getting the close ups of the team coming through the door. (00:32:00)
Other mistake: In the opening scene, the car has a Florida license plate visible on the front. Vehicles registered in Florida (and eighteen other states) don't have plates on the front.
Character mistake: When they are delivering the profile, Rossi says "he's already picked his next victim; an adolescent boy." The victim is a girl.
Suggested correction: Rossi is talking about the next victim after the girl.
Other mistake: When Hotch, Morgan and JJ review the footage from the first murder, they are able to zoom extremely close on the victim's hand. Why don't they do the same with the car license plate as the killer leaves? (00:21:45)
Audio problem: Garcia is typing on a flat, foldable rubber keyboard but the keys' sound is loud like from a plastic keyboard. The rubber keyboard shouldn't make noise. (00:39:00)
Continuity mistake: When Garcia accesses the bank's page online Prentiss gives her the account number login, 1552 9384 6729, and we see Garcia typing it correctly on the screen with the password, but when it cuts to the account's page showing deposit and balance, we see in the balance box the account number's last four digits are 7629, not 6729.
Won't Get Fooled Again - S1-E3
Audio problem: The video game Penelope is playing is supposed to be Tetris, but the sound effects are from the Atari 2600 version of Pac-Man. You can hear Pac-Man die four times during the scene. (00:12:20)
Other mistake: When the character is buried alive the psychiatrist pours bags of dirt on the head of the victim. First, there is a pile of bags that shows only 8-10 bags of dirt, which is not enough to fill the hole. Secondly, the victim was conscious and standing up with no apparent broken bones, which means she could have just stood on the dirt as it was (very slowly) poured in. Additionally, she was buried completely during the entire time the murderer was evading police, having a conversation with Hotchner, and jumping to his death. Then the BAU talked about their suspicions she was still there and had to make it all the way to the basement. She would not have had a "faint pulse" after all of that time.
Visible crew/equipment: After Prentiss and Morgan catch Eric and his girlfriend in the park it cuts to Prentiss and the girlfriend in the interrogation room, and as the camera tracks backward from the door's window we can see a nice reflection of the moving camera and also a crew member standing behind Hotchner.
Continuity mistake: When Rossi is in Zoe's bedroom the camera pans the room and we see the laptop on the desk with nothing on its lid, but in the closeup suddenly there's a large embroidered flower sticker on the laptop's lid, which vanishes again when Rossi lifts the lid.
