Other mistake: When Jack first arrives in Christmas Land he doesn't know what is falling from the sky (snow) but he somehow knows that the children are throwing snowballs.
Other mistake: After the Sanderson sisters are done sucking the life out of Emily Binx, they do a little dance thing after they become younger. When either Winifred or Mary swings past her, Emily's leg moves even though she's supposed to be dead. She's also playing with her hands and bobbing her head.
Other mistake: During all of the Battle Scenes there isn't nearly enough blood on the swords. This is most apparent in the last fight.
Other mistake: The wizard Eusaebius is searching a slug powder to make the potion. When he finds it, it's a liquid.
Other mistake: In the last game, Chet pitches six innings ("You gave me six great innings!"), then Henry takes over pitching, meaning he'd be pitching in the 7th inning. Sounds good, until we fast forward to the 9th, with Heddo batting with two outs... Assuming Henry was perfect, Heddo would be the 9th batter Henry faced, meaning he would've been Chet's last out in the 6th, which of course he wasn't (the Chet play at the plate ended the 6th and he wasn't facing Heddo.) Also, Heddo was seen walking up to the plate after the second out of the inning (the rundown at second base), with Martinella saying something like "holy goosebumps, it's Heddo" as he approached. Heddo would've been on deck, so it wasn't a surprise, plus he would've already been at the plate prior to the rundown play.
Suggested correction: There is a reasonable explanation for both of those points. Heddo could have been a substitution player after the sixth inning, or be a pinch hitter, so hadn't been to bat yet. This would be logical since Heddo is a fastball hitter and they think Henry is still throwing fastballs, so as a last ditch sent him in. For why they didn't notice that Heddo was on deck, they were captivated by the on-field action, and with Henry off the mound going over by first base and doing stupid stuff, hadn't looked over yet to see who was next.
Other mistake: On the second day, Phil did his same tasks at about the same time as the previous day, so everything lining up the same made sense. However, on day 3, he quickly rushes out of his hotel, avoiding interacting with most of the people he did before and gets to the street with the beggar much sooner than he did before. Yet Ned still is there crossing the street and sees him exactly the same as before. However with Phil having skipped so much he would have gotten there and passed that spot a good while before Ned would have gotten there, and they should not have had the exchange again on day 3. Same thing for when he arrives at the Groundhog Festival, with Rita greeting him like he's late. But he would have gotten there much sooner this time.
Other mistake: Toward the end, Pubert escapes the crib and is crawling away from the camera. It can be easily seen that it's an animated puppet due to the even movements. A second later, you see the live baby, and the movements are nothing like a moment before.
Other mistake: Before Jack's car jumps over the bridge, a van skids on the road. The first angle shows a thug firing at Jack, and the second angle shows Jack swerving to the left to dodge the bullets. The editing is all wrong here: The thug fires at the opposite lane to where Jack is, so he is really driving to where the bullets are.
Other mistake: In the police car chase after the prison break, Mario lets go of the wheel to prove a point to Luigi. In doing so, their police car rams head on with a civilian car, causing the police car to ramp up and stop on top of the civilian car. Normally, this could theoretically happen. However, in that world, the police cars are fitted with a snow plow like thing on the front of the cars, with an angle to them. The way the cars hit, it is not possible for the police car to have hopped up on top of the civilian car in such a manner. If anything, the snow plow would have caused the civilian car to ramp up on the police car.
Other mistake: After Leonardo revives Yoshi, he picks him up, hugs him and touches heads with each other as they hug but Yoshi pretty much moved his head immediately and Leonardo continued sitting there as if their heads were still touching. It looks like the actor didn't realise the child moved away and they never reshot it. (00:48:15)
Other mistake: After the Leprechaun has used the small car with the pitchfork and rammed the pick up truck, it rolls down the hill 3 or 4 times. The leprechaun opens the door and all 4 characters are not in the vehicle. They have not only managed to all exit the vehicle and hide behind a boulder but have all managed to not receive so much as a single scratch and Jennifer Aniston's hair is still perfectly brushed.
