Other mistake: In both the books and the movies, Harry's Invisibility Cloak can always be seen until it is worn. In Diagon Alley, just before the Gringott's break-in, Ron pulls out the cloak to cover Harry and Griphook, but it turns invisible before he puts it on them. Ron merely mimes the motion of covering them.
Other mistake: On one of the SHIELD monitors, "perimeter" is spelled "perimiter".
Other mistake: Emmett states that the Cullens "haven't hunted in weeks", meaning all of the vampires should have black eyes. However, all of the actors still have their golden contacts in. This is especially noticeable on the Blu-Ray.
Other mistake: In the beginning the guy cuts a triangle in a banner, but the inside piece is floating.
Other mistake: Theseus spends a whole minute swinging his axe at the log with absolutely no effect. (00:06:50 - 00:07:55)
Other mistake: To get revenge against the reds for chopping off his hat, Benny goes inside the house to use the computer to change the woman's lawn mower order. Benny never hits the 'ENTER' key to complete things. Things are completed when he steps on the 'SPACEBAR'. Same thing happens later when Benny is ordering a female flamingo.
Other mistake: In the cave, Angélica steps out of the water and in the close-up of her face her hair is dry, and even drier in the following close-up.
Other mistake: When EB is playing Rock Band, the TV shows the drum playing rapidly, but EB is playing the same beat he was before the solo.
Other mistake: As Johnny looks down on the wrecked car after defeating the devil, we see a blank brake disk without a wheel on. I guess it would theoretically be possible for all five lug nuts to rip clean off during an accident and leave the brake disk bare and exposed. But then the threads in the disc would still contain the shorn-off remnants of the lug nuts, instead of being empty. (01:23:00)
Other mistake: The protagonist uses his belt to temporarily fix the movie projector. He has to keep his pants on with his hands, but that's only until he has to grab an object and the pants do drop. Then he is still belt-less but the gag ran its course and his pants are not falling off anymore, once was enough.
