Visible crew/equipment: When the horse carriage is ambushed, just as Princess Abigail can be heard screaming "Please, help me", the camera pans downward and a horse wrangler wearing a blue baseball cap can be seen in the lower left hand corner, hiding behind one of the horses. (00:03:20)
Continuity mistake: When Megan is running late to pick up her daughter and friends from a sleepover, she arrives in the medical examiner car with Peter. The girls walk towards the car. Megan then gets out and introduces herself to the friends. The girls dump their bags on the ground and the two friends go to get in the car. Her daughter stands by the bags and asks 'who are you?!' to Peter. He explains who he is and that he works with her mum. - however in a previous episode her daughter goes to her work place and interviews all the staff, including Peter. (00:17:35)
Continuity mistake: When Emma and Zuri are watching the horror doll movie, Jessie comes in for a little bit and you can see that the popcorn bucket is completely full, but after Jessie leaves and they see the part with the eye, Zuri puts an empty popcorn bucket on her head. Wasn't there popcorn in it a few seconds ago?
Other mistake: After the turkeys start attacking in "The Running of the Turkeys", Mr. Fishoder and his brother start running. In that clip a Turkey pops out the side of a guy's head. Look in the mid lower right side. Looks like a design error. Pretty big error, no slow down needed to see it. (00:05:20)
Revealing mistake: When Cathy and Gaston return to the house to find Betty, Father Damien and Annette Curtain high from the chocolate brownies, she asks where Mrs. Brown is and she tells Cathy that she is upstairs wandering around since she is high. Cathy then tells her to come back downstairs and Mrs. Brown replies a few seconds later saying she is coming back down and flies down the stairs in the chair lift. Before Mrs. Brown comes back down, she can actually be seen sitting in the chair lift at the top of the staircase, from the moment where she tells Cathy she is upstairs to the moment where she says she is coming, waiting for the cue to come downstairs.
Factual error: When Tom has decided his scout group will have to go for the food and then his look for his son later, they are stood on a green. There is a war memorial dedicated to both World Wars, 1914 - 1918 and 1939 - 1945. That's got to be in Canada, as the USA didn't enter either war until later than those dates. (00:28:00)
Continuity mistake: At the bowling alley after Jim bowls and walks back to the group and talks to them, we see a young man in the background with a grey top about to bowl. Then there is a quick shot that cuts to Adam and, then the shot cuts back to Jim and the guy in the background is about to bowl again.
Continuity mistake: When Schmidt and Robbie are spying on Cece's date, Schmidt sits down at Robbie's table to his left and after they both admit that they are still in love with her they bring it in for a hug.
