Continuity: In the scene where Howard is 'going to work' and Jamie is trying to talk him into staying, at first the cereal bowl has only a little bit of cereal. Then in the next shot, it is almost full again.

Factual error: When Howard runs into Ted and the reindeer, the reindeer's antlers are still in velvet. Velvet is shed in August, at least four months before the Christmas Eve setting.

Continuity: In the scene with Sinbad and Howard in the radio place, Sinbad gets enraged, then throws the package (thought to be a bomb) and Howard hits the deck. The package lands at Howard's head, but in the next shot, it's way over to his left.

Factual error: When Howard is running after the bouncy ball he is on the second floor of the Mall of America, however, you see him run through the LEGO store which is located on the lowest floor of the Mall of America, which is impossible if he was on the second floor before.

Continuity: Howard knocks the wiseman's head into the fire. In the wide shot before he notices, the head is no longer in the fire, but in the next shot, it is once again in the fire.

Continuity: When Howard is first talking to the Santa in the department store the Santa tells him to "...Have a little respect for the beard" then part of it slides off like it was glued on. He then sticks it on again. Problem is, when they are fighting at the conmen's hideout, he takes him down by pulling his beard - that is now held on by an elastic cord and snapping it back. Granted it is not the same scene, however the only thing that happened between these two shots is them driving to the hideout and he would have had no reason to change it.

Continuity: When we see Howie reach his hand to pat the reindeer, he is clearly wearing gloves. As the reindeer snaps at his hand, we see he is no longer wearing gloves.

Continuity: When Howard is breaking into Ted's house he uses a credit card to get in. The camera shows a close up of the lock and door knob from the inside twice, both times you can see that the door is not shut properly.

Continuity: In the scene where Howard is in Ted's house stealing the Turbo Man doll, and he catches the wiseman on fire, we see a shot of carollers outside. The ground is covered in snow and the sky is overcast. Howard then kicks the wiseman's fiery head out the door in the direction of the carollers, and the carollers scream and run away. It is now sunny outside and most of the snow is melted.

Continuity: In the scene, when Liz (Rita Wilson) is making cookies, Ted (Phil Hartman) comes in. In the shot, when she is scooping the cookies off the baking tray onto the plate, she only has 1 on the plate. The camera then goes to Ted, and in the next shot, nearly all of the cookies are on the plate. How could she have done that so quickly? They were so neatly arranged on the plate, and none were broken.

Factual error: When Howie's (Arnie) vehicle breaks down, he's on a landmark bridge in Minneapolis, crossing the Mississippi River at Nicollet Island. He's at essentially Zero Hennepin Avenue, Minneapolis, as the river is the dividing line between East and West Hennepin. He pushes the car off the end of the bridge and rolls to a stop at a diner. This is the landmark Mickey's Diner in downtown Saint Paul, some ten miles away, the one located at 36 Seventh Street West. Howie should have looked even more exhausted than he appears in the film.

Continuity: At the end of his jetpack flight, Howie is diving headfirst straight down towards the ground. Then when the camera changes shot to see his landing, he hits the ground at a completely different angle, on his back. Furthermore, he suffers no injuries - that costume must be very well padded.

Continuity: At the part where Howie is in the neighbours' house "stealing" the Turbo Man the head of a statue catches on fire. He tries a couple of times to get the fire out. In one shot the head is right next to his foot and in the next shot the head is gone. Then in the very next shot the head is back and he kicks it out the window.

Revealing: Certain parts of this film were made during the fall months, not winter. In the background of the high up shots during the parade, leaves can be seen on trees (in the distance). Also, the grass is surprisingly very green, in several locations.

Plot hole: Near the end of the movie Howie dresses up in a Turbo Man costume, with real working discs shooting out of his arms, and a real working jetpack loaded with fuel on his back. It seems unnecessarily extravagant for a costume, unless the real Turbo Man actor was supposed to do some kind of a stunt as part of the show - but that would have been very dangerous in a public place with no wires or safety net.

Continuity: During the parade you can clearly see trees in the background with plenty of green leaves.
