Homeless for the Holidays - S3-E10
Revealing mistake: When Mark goes to treat his cut, he leaves the lounge with a couple of tissues held to his head. He gets some supplies and puts a supposedly fresh piece of gauze to his forehead - however the gauze already has some "blood" on it - a feature the camera obviously wasn't supposed to catch. When Jeanie comes over to check it out, he pulls the gauze away from himself and - voila - there's the bloodstain.
Homeless for the Holidays - S3-E10
Character mistake: When Doug leaves work, he tells Carol he is Going Home to watch the channel 11 Yule log. Later on, he shows up at her house with Charlie and Carol says, "I thought you were watching the channel 9 Yule log." It's possibly a slip of the tongue from Carol, but most likely it would be ingrained in their heads which local channel features a Yule log at Christmas.
Night Shift - S3-E11
Continuity mistake: When Carter and Doyle are running down a corridor to the patient having a heart attack, the camera follows them along the floor and you can see several coloured lines going down the hall. After we see this, they burst through a double door, and if you look behind them you cannot see these lines anymore; they've simply vanished.
Post Mortem - S3-E12
Continuity mistake: When he's scuffling with the homeless man in the trauma room, Carter's stethoscope slips off his shoulders and drops to the floor. By the time Mark finds him standing outside, it's back around his neck, with no moment when he could have picked it up.
Continuity mistake: Benton is talking to Carla about her preganancy test and they go through the double doors to the snowy outdoors. Carla has nothing in her hand when she pushes the doors open, but once outside she is holding a hat - she wouldn't have even had time to pull it out of her pocket.
Continuity mistake: Dr. Hicks is standing in front of the surgery white board talking to Carter and she says "Care to join me?" He replies "Love to" and the shot goes right back to her - she has moved 8 or 10 inches to the left, without enough time to have done this in real life.
Continuity mistake: Carter is watching the clock, waiting for Peter to show up for a presentation. The clock jumps from 3:03 to 3:04 in a Split Second (we literally see the minute hand jump)but the second hand doesn't change posiiton.
Continuity mistake: When Peter signs the consent form for his surgery, his head is raised off his pillow a few inches. The shot changes and he continues to sign - but now his head is lying on the pillow even though he didn't have time to move.
Continuity mistake: When Mrs. Novotny offers to get aspirin, Angie helps her up by Mrs. N.'s left hand - there's no blood on it, but the next shot shows her hand quite covered in dried blood. Mrs. N. has no blood on her clothes, despite being right next to her husband while he bled to death and Carol administered CPR.
Continuity mistake: Carol is working on James' injury and Duncan goes to answer the phone. James has his arm wrapped around the phone but the shot changes to focus on Robert - we can still see James but his arm is now at his waist, even though he had no time to change positions.
Continuity mistake: While Carol is trying to save Mr. Novotny's life, Mrs. Novotny's hair alternates from being loose and hanging over her cheeks to being neatly tucked back into her bun. In fact, a few minutes later when Carol asks for her keys, her hair looks just-brushed shiny and newly coiffed - it's unlikely she would have fussed over her hair at this stressful time.
Continuity mistake: Kerry follows Carol outside and as Carol is holding her gloved hands up in front of her Kerry asks her if she needs anything, and as she replies, "No thanks, I'm fine," her hands are suddenly in her pockets.
Plot hole: Carol and Duncan escape out the back of the shop - but there are no police waiting for them, which makes no sense at all. In reality, with such a situation, the police would have been waiting at the back door. There seems to be no one around at all, as they were able to dash through an apartment. When they finally do run into a cop, he automatically assumes that Carol is an innocent bystander, and not one of the robbers. He couldn't have known this, and in reality, a policeman wouldn't assume it.
Continuity mistake: Carol is putting little bandages on Duncan's face and we see her put 2 on his forehead and 3 on his cheek. The shot changes and now there are 3 on his forehead and those on his cheek have shifted position slightly.
Continuity mistake: When Carol is talking to Angie in the hospital, there is quite a large bloodstain on Carol's sweater, just below her left shoulder. She leaves the room, meets Doug, and without explanation, the bloodstain has disappeared.
Continuity mistake: When Mark is examining Louise, her Barbie changes position several times from shot to shot.
Continuity mistake: Carol sits down at the breakfast table in a normal sitting position, however the next shot shows her with her knee up on the chair, almost up to her chin.
Continuity mistake: Mark is talking to Maggie about getting Louise on the transplant list - he has his arms clasped in front of him with his hands wrapped around his elbows. The shot changes and his right arm is outstretched with his hand on the wall - with no time for the change.
Random Acts - S3-E20
Revealing mistake: When Dr. Greene is being attacked in the toilet, he is thrown into a supposedly brick wall. It bends and wobbles like a set wall would.
Random Acts - S3-E20
Continuity mistake: Chris Daw confronts Mark in the parking garage with the bill from the hospital for his brother's care. Mark folds up the bill, but as Chris says, "They don't understand", the bill is suddenly open in his hand again.
Answer: Take care of your dad.
