Continuity mistake: During the drunken gymnastics young Miss Langford is doing to the delight of the paparazzi, she is wearing transparent pantyhose for the most part of the scene; you can see it during the cartwheels with the panty shot, and with the feet close-up. However her legs and feet are bare when the camera shows a stuntwoman leaping over the gifts and crashing into the tree (probably they didn't want to tear the stockings with that landing). (00:02:30 - 00:03:55)
Continuity mistake: Back in the kitchen, after hearing Ellen's silly egg story Debbie takes the station and starts telling her that she knows who she is. Necklace and apron are separated at first, one on top of the other at the cut. It happens again at the end of the conversation, when there's again the front view of both. (00:41:25)
Continuity mistake: After failing to tip the bus driver, Ellen moves the blue suitcases out of the way a bit. The taller trolley is in front of the other. When the man with the Christmas tree walks by knocking the Paris one into the street, the two trolleys have changed position. It should also be noted that she points out that "some guy" hit her suitcase - but the guy is nowhere to be seen afterwards - kinda hard to imagine him rudely sprinting away leaving her in that predicament...while carrying a tree. (00:15:40)
Continuity mistake: When Ellie puts on the front desk the box for Zeke, from behind she has her hands on top of it, but in the reverse shot she has her hands on the sides and only then she joins them together on top. (01:23:20)
Continuity mistake: When Ellen offers "Why don't you guys take the bed?", the mom turns around suddenly being all "Holy sh*t!", with nothing in hand. When she actually answers in the next shot, she is holding a pink garment. (00:50:20)
Continuity mistake: In her trip getting items from the local stores for the charity auction we see Ellie driving a car so stuffed with gifts that she needs to keep the trunk open. That's from the second store she is shown hitting. When she manage to extort a computer from the Apple store, the trunk is closed. (01:04:20 - 01:06:20)
Continuity mistake: The morning after her unceremonious landing into the Christmas tree, Ellen's dad is holding the tabloid with the full story. In the very first close-up of the first page he is holding it with his left hand. What follows is a wider shot of him holding it with both hands. (00:04:25)
Continuity mistake: In the close-up of Ellen's phone that shows that yes, there is no signal in the town she's in (go figure), her thumb is at a lower position than in the previous and the following shots. (00:17:00)
Continuity mistake: In the back room of the guest house, Ellen picks up the little notepad with Jake's sketch. She is holding it with the left hand in the top part and the right hand placed lower. When she says "That's adorable" she is holding it the opposite way, and at the cut is back as it was. (00:54:40)
Continuity mistake: Ellen puts in the oven a tray; it has two gingerbread men with blue sprinkles in what is the bottom left corner (upper right of the screen). When she opens the oven, she pulls out a tray with gingerbread men that perfectly alternate between red and blue. (01:03:20)
Continuity mistake: Ellie drives to the hotel a car loaded with gifts. Look at her scarf when she joins Jake and the sheriff in front of the building. Look at her after the cut showing the car. It's like she took her scarf off and wrapped it differently around her neck during that couple of seconds. (01:06:30)
Continuity mistake: When Ellen's dad asks her to hand him the credit cards, she is turning towards him almost fully, but in the reverse shot she's still holding her cart, facing forward with her body. (00:12:20)
Continuity mistake: Ellen received the mission from her dad. He boyfriend is opening the fridge door, which contains a lemon. The lemon is in a different position at the cut. Moreover, in that new shot he is holding the bottle in his left hand, but he holds it with both in the front view that follows. (00:09:20)
Continuity mistake: Talking with Alice after his morning chat with his daughter, Jim asks her if she thinks he spoiled Ellen. Doing so, he hands her the document he just signed. And of course, he hands it to her using the left hand in the first shot, which turns into the right hand in the reverse shot. (00:06:35)
Continuity mistake: When Gray mentions "Karen from accounting" to Ellen during the first call, she has two fingers reaching around the microphone in the side view, but she is grasping the handset with all fingers together in the previous shot. (00:33:50)
Continuity mistake: When Ellen's dad is heading to his office in the morning, his assistant is reading out loud to other employees the article dealing with her party hijinks (the only sentence on that prop that talks about that subject, by the way). Behind her in there's a woman holding a blue clipboard - she is holding it with the right hand on the corner in the close-up, while it was the left hand in the shot before. (00:04:35)
Continuity mistake: Ellen loads the biscuits in the trunk of the car as Debbie tells her about Mr. Martin. When she says "I will", her foulard is caught under the chain of her bag. In the reverse shot the foulard is draped above the chain and in different position. (01:03:45)
Continuity mistake: After her display of gymnastic (and underwear), Ellen receives the charity donation from the party guest. She says "Toys for Tots thanks you for your generosity"; at the first word she is switching hand position from the top corner of the check to the bottom corner. But at the cut, she is holding it again by the top corner. (00:03:00)
Continuity mistake: Ellie is about to tell Jake the truth about her, but he is called away to help fix some part of the stage. The woman with the cap is screwing the mock house roughly at the point where Jake is holding the column. At the cut her hand moved at the top of the archway. (01:13:00)
Continuity mistake: Gray blurts out at the bar Ellen's real name. Jake realises who she is, and there's a reaction shot of Gray realizing he messed up. The olive stick in his martini is in a different position than in the rest of the scene, so is the level of the drink. (01:20:05)
