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)
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.
Continuity mistake: While Reid's asleep in the hospital bed, Garcia places four Doctor Who figurines (one Dalek we don't see her place) on the overbed table - two Daleks, Matt Smith's Doctor, and David Tennant's Doctor. In the first shot Garcia's holding Smith's Doctor in her right hand and Tennant's Doctor in her left hand, but in the next shot those two figurines have switched hands.
Visible crew/equipment: When James Charles, the guidance counselor, says, "It could be someone you know, or it could be a stranger you pass at the grocery store," the actors' red T-marks are visible on the floor at Reid's and Gideon's feet. Then when Charles continues to say, "gathering information on the case," we can also see the actor's white T-mark beside the counselor's feet, where he will stand after he introduces Gideon.
Exit Wounds - S5-E21
Factual error: The BAU is called in to assist the Sheriff's Dept. in Franklin, Alaska (a made-up town, although there is a ghost town by that name). By statute, Alaska has never had any Sheriffs. Functions filled by sheriffs elsewhere fall mostly under the auspices of the Alaska State Troopers. Other law enforcement is by community or (rarely) borough which is what Alaska has instead of counties.
Continuity mistake: In the elderly victim's home, when Gideon is going through the dresser drawers he finds the small frame with the picture of her son, and there is a blue frame lying in the drawer, but in the next shot that blue frame is lying on the dresser even though he never touched it. (00:02:10)
Other mistake: When it shows Keri's license it says it expires in 2003, but the episode takes place way after that year, considering Katrina had already happened.
Continuity mistake: At the start, JJ puts a file down on the desk, and her left hand is in front of her, and she has 2 items in her right hand. When the camera angle changes to behind JJ, her left hand is now on her hip. (00:02:20)
Continuity mistake: When Reid disarms Maggie, he has his hand on the gun but no thumb on the hammer. When the shot changes to Maggie's POV, he has his thumb on the hammer. (00:37:20)
Revealing mistake: When the suspect is first put in handcuffs at the house, it's clear to see he is just holding the one cuff rather than wearing it. (00:27:50)
Continuity mistake: When Reid tells Lila that her manager is dead, he has his hands on the back of his neck. When the shot changes, his arms are now lowered and under the water. (00:27:00)
Continuity mistake: When Lila gets the note that was taped to her door, she holds it by the side in the close-up showing the contents of the letter and from the top when she is crumpling it up. (00:15:30)
