Character mistake: When Delia is rushed out of the shop at closing time by Melinda she is wearing gold long 2" chain earrings. When she gets to her vehicle and reaches for her gift she is wearing gold filigree hoop earrings.
The Walk-in - S2-E17
Continuity mistake: When Jim brings a new body to the morgue there's a "John Doe" already lying there, and in the close up we see that the corpse's right foot is missing the middle toe. We see this again later when Jim's ring is stolen from his locker, with the bloody right footprint on the floor. However, when Melinda shows up the close-up shots of the bloody footprints have been flipped so it's the left foot with the missing toe, but what's funny is that in the audio we hear Jim say, "The middle toe is missing on the right foot."
The Walk-in - S2-E17
Revealing mistake: When Jim and the mortician are about to transfer the dead guy from one table to the other, his arms move slightly.
The Prophet - S2-E21
Continuity mistake: Melinda calls Deliah early in the morning. Her husband just said it was 4:10 and she called her friend who also said it was 4:10. Deliah looks at the clock and confirms the time. But as the camera pulls back, the minutes on the clock are visible, showing 22.
Continuity mistake: At the beginning of the episode when Jim and Melinda are watching the last of the movie, at one point Melinda takes a drink of her beer and crosses her arms twice but from a different angle.
Continuity mistake: When Jim joins Melinda on the bench to discuss the treatment records from Gabriel's institution, the heart locket on Melinda's neck keeps vanishing and reappearing repeatedly, depending on the angle of the shot. (00:07:50)
Continuity mistake: After Delia and Melinda are at the house in the countryside the episode cuts to a scene at Same As It Never Was Antiques. In this shot out the front we can see Melinda's 2005 Jeep Liberty Limited edition parked, but Melinda hasn't had this since the first episode of season 3. From Season 3 episode 2 Melinda can be seen driving a 2007 Saturn Outlook XR. (00:04:50 - 00:39:51)
Revealing mistake: When Melinda goes to Justin's dorm room to speak to him after he dies, the camera pans to his body on the bed and you can see that it's a body double. (00:24:50)
Firestarter - S4-E1
Visible crew/equipment: When Eli is at McShay's bar he hears the ghost beside him say, "Day after day after day," then when the bartender speaks to Eli, in the wide shots the shadow of the boom mic is visible right above the mirror. After Melinda walks in, when the bartender tells her that Eli scared all his business away, we can see in the mirror's reflection the boom mic dipping into view.
Imaginary Friends and Enemies - S4-E6
Continuity mistake: In the scene in the woods where we first see Owen's ghost, as the camera cuts back and forth between Melinda talking to Owen and what her friend sees, the two women are alternately closer and then significantly farther apart. They're supposed to be standing basically in the same spots, only taking maybe one or two small steps during Melinda's conversation with Owen.
Plot hole: Jim taking over Sam's body just doesn't make any sense. It's plausible for a spirit to temporarily take over a living body, but a dead body is dead for a reason. It can't sustain life anymore. Death isn't a temporary ailment. It's permanent. What should have happened was the same thing that happened when another ghost took over a recently deceased person, which happened in a previous episode. The dead body would decay and start to lose function. Sam's body suddenly gaining back the properties of life is completely inconsistent with what we're led to believe in the setting of the show.
Suggested correction: This is a fictional show that pushed the boundaries and constantly changed the rules; how is this a mistake?
I tell myself that Sam's injuries were not as extensive as prom ghost so his body was able to stay alive.
I think what happened is that Sam jumped out and went into the light before they were able to revive him. Had he waited just a few more seconds next to his body He would have gone right back in. Some people die for a few seconds, and then they're able to bring them back through CPR or using the paddles and shocking his heart, etc.
Heart & Soul - S4-E8
Continuity mistake: After Sam reads the newspaper article about Jim's death it cuts to him dropping in to see Melinda, and when he's looking at the framed photographs on the sideboard two of the closeups of the photos are flipped shots - the positions of the frames are reversed.
Visible crew/equipment: When Melinda heads out to go on a run, while she and Sam/Jim are standing beside her car, in the shots facing Sam/Jim we see Jim's face, actor David Conrad, and in the car window's reflection we see Sam's face, actor Kenneth Mitchell, which is deliberate for viewers since Jim's spirit is in Sam's body. But just as Melinda says, "He worked a lot of weird hours, and liked to sleep-in a lot," it's amusing that in the reflection we can see both actors - David Conrad walking and then standing behind Kenneth Mitchell, both of whom play the same role and are wearing the same grey T-shirt.
Visible crew/equipment: After Sam/Jim tells Melinda that he'll be leaving and doesn't know how long he'll be gone, as he drives away the reflection of the large reflector screen can be seen on the pickup's vent window.
Continuity mistake: While Melinda's trapped underground with the rising water flooding the utility vault, when Eli and Jim go down below Eli takes off his shoes and jacket, the camera pans up from the churning water and we briefly see Eli's bare feet. The next shot we see him taking the socks off.
Continuity mistake: When Eli tries to use a card to open Zoe's door, the card breaks. He is holding on to the larger piece of the card in his right hand when this happens and the smaller piece is in the frame. He gets the other piece and the shot changes to him suddenly holding the smaller piece in his left hand, as well as the card having been flipped around (the strip is seen in both shots, and the two shots face in opposite directions).
Character mistake: When Aiden and Melinda go the the hospital to visit Jim/Sam the picture on the hospital badge is of Jim Clancy not Sam Lucas... Jim has been in Sam's body for many years at this point. You can see the badge multiple times in the episode.
Character mistake: Jim is at the hospital - at the end of his phone conversation with Melinda, someone calls out "Dr. Clancy" when the character is Sam Lucas. (00:09:15)
Other mistake: In the scene immediately after the opening credits, Jim is talking to Melinda on the phone. Right as he's hanging up, someone calls out "Dr. Clancy? Got a minute?", to which Jim waves in acknowledgement and starts up the stairs. (Jim's spirit has been in Sam Lucas' body since season 4 and in an earlier season 5 episode, his white coat is embroidered S. James Lucas, M.D). (00:09:15)
Continuity mistake: After Jim and Aiden surprised Melinda with the new SUV Melinda drives off in the red vehicle, but when Aiden and Jim do their fist bump it cuts to a closeup of Jim, and the red SUV is still parked beside Jim.
