Mr. Monk Meets Dale the Whale - S1-E4
Revealing mistake: When Monk is showing how Dale and his Doctor murdered the judge one can see that the knitting of the right chair is already cut to ensure that the policeman will fall through it when he later steps on it.
Mr. Monk and the Red-Headed Stranger - S1-E12
Revealing mistake: In the scene where a man is streaking, he is carefully made to look naked. But when he is running through the park, there is one shot where you can see some black underwear.
Mr. Monk Takes Manhattan - S3-E1
Revealing mistake: Monk's reaction to the gunshots begins just before the gunshots go off. (00:03:55)
Mr. Monk and the Panic Room - S3-E2
Revealing mistake: Throughout the episode, the panic room door is made to look metal. But later when a hole is cut in the door, you can easily tell by looking through the hole that it is wood.
Mr. Monk and the Panic Room - S3-E2
Revealing mistake: In the scene where Darwin and Monk are in the kitchen and Monk calls Dr. Kroger. Darwin pulls the phone out of the wall, but there is no line from the phone to the jack in the wall.
Suggested correction: The phone is a wall type that connects directly at the back. The jack on the wall is wired, and the phone connects when it's mounted. This was a feature of many wall mounted phones as you didn't want exposed wires.
Mr. Monk and the Red Herring - S3-E10
Revealing mistake: When Julie's teacher is searching the name 'Larry Tilburn', he isn't typing into a search engine, virtual encyclopedia, or anything of the type, the computer just shows a blue screen with a popup message in the middle.
Mr. Monk Gets Stuck in Traffic - S3-E13
Revealing mistake: The VW Beetle that slides out of the dump truck and rolls over is noticeably not the same car the victim was driving earlier. It's a lighter color, and is already badly dented, even before it's wrecked.
Mr. Monk Gets Stuck in Traffic - S3-E13
Revealing mistake: When we see a shot of Steve in his car while in the dump truck, it's shot in a studio and the shot is reused each time we see Steve in the car. The shadow is completely different and at one point, when they show Steve in the car with the car and truck bouncing around, you can tell the image is just shaken, rather than the dump truck actually bouncing. There are loose chains hanging off the inside walls that don't move or sway at all.
Mr. Monk Goes to a Fashion Show - S4-E10
Revealing mistake: The fan letter Monk wrote to shirt Inspector 8, shown in close-up where it hangs on her work station wall, consists of the same paragraph printed out twice. (00:06:45)
Mr. Monk and the Captain's Marriage - S4-E12
Revealing mistake: In their efforts to hide Gerald's pet mouse from the hospital staff, Randy and Natalie toss the rodent back and forth and alternate hiding him in their pockets. But every time he's tossed, Devo the Mouse gains weight. In fact, Devo's (stuffed?) stunt-mouse double is at least twice Devo's actual size. (00:27:00)
Mr. Monk and the Leper - S5-E10
Revealing mistake: When the balloon goes over the cliff, a very obvious dummy replaces Monk.
Mr. Monk and the Leper - S5-E10
Revealing mistake: Look at the stuntman who stands in for Tony Shalhoub when the balloon crashes and the basket scrapes and bumps along the ground. He is about fifty pounds lighter than Shalhoub, looks nothing at all like him and his hair looks like a Harpo Marx fright wig dyed black.
Mr. Monk and the Leper - S5-E10
Revealing mistake: When Monk is hanging from the cliff, in the shots looking down at Monk you can see the ocean through him.
Mr. Monk Makes A Friend - S5-E11
Revealing mistake: During the fight in the kitchen, piles of plates are knocked to the floor. The plates that we see hitting the ground all remain intact. Nevertheless, we hear the sound of plates smashing, and when the aftermath is shown, there is broken crockery everywhere. Clearly the plates used were made of plastic or some other unbreakable substance to minimise injury to the actors and stuntmen.
Mr. Monk Makes A Friend - S5-E11
Revealing mistake: During the fight scene in the restaurant kitchen you can see that the woman is a stuntman, you can even see the horrible wig pop up off the stuntman's head a few times.
Mr. Monk Goes to the Hospital - S5-E16
Revealing mistake: When Monk and the others are examining the crime scene, the "corpse" can be seen breathing (his abdomen is rising and falling) and blinking. There are various shots in this scene taken from behind the body looking into the room, and some of these are pulled back so that the body is visible while others are zoomed in so that it is not; this is not a mistake, but suggests that maybe the actor was told he would not be visible in these shots and so did not need to hold his breath.
Mr. Monk and the Daredevil - S6-E7
Revealing mistake: When Monk, Natalie, and Joey are fighting on the roof, the end of the metal pipe in Joey's hand wobbles around a lot, as if the pipe is made of rubber. (00:37:20)
Mr. Monk and the Daredevil - S6-E7
Revealing mistake: Watch as Natalie fights with Harold's cousin on the roof. The same shot where she's barefoot, she's also got thicker hair, indicating a wig on a stunt double.
Mr. Monk and the Wrong Man - S6-E8
Revealing mistake: During the fight between Max and Paulie, the stunt double for Paulie is easy to spot - he has a full head of dark hair, whereas Paulie is gray and largely bald on top. (00:23:30)
Mr. Monk Joins a Cult - S6-E11
Revealing mistake: When Monk and Natalie are talking to the cult members, a Culver City bus can be seen driving in the background, which is a Los Angeles bus, but the show takes place in San Francisco. Culver City is home to a lot of movie shooting. (00:09:15)
