Revealing mistake: When Austin enters the bathroom at the casino, keep your eyes on the door during the scene - it opens by itself before closing. (00:31:10)
Revealing mistake: In one shot when the boat is pulling away from the waterfall, you can clearly see that the shot is the same one they used earlier in the movie. The water from the waterfall now is going up the cliff! They have just put it in reverse.
Revealing mistake: When Sarah is making her way to the baby Stego, just before she gets on her belly and crawls closer to it, you can see the kneepads she has on.
Revealing mistake: At the end of the Sub-Zero vs Scorpion fight, Liu Kang jumps over to help Sub-Zero and Scorpion teleports away. A few moments later you see a shot where you see all the actors, (Liu Kang, Sub-Zero and Kitana), if you look closely you can see Scorpion waiting in the background just waiting to pop up and snatch Kitana.
Revealing mistake: Right after they "create" Leeloo and she is lying in the plastic cage with the little straps on her, the guy approaches her and says, "if you want out, you are going to have to work on your communication skills." She gives him a dirty look, and then you can see a huge hole, pre-cut in the glass, that she busts her hand through. (00:29:47)
Revealing mistake: In the scene with the helicopter chasing them down the street, apart from the fact that the rotors should catch on something and hurl the machine into a wall, when it finally hits the wall at the end, the pilot and crew quite clearly become about 4 crash-test dummies. This wouldn't be so bad if it weren't for the fact that they are unpainted and all sit in their seats looking straight ahead with their hands in their laps while they are driven into a wall. You'd think they could have at least posed the arms over their faces or SOMETHING!
Revealing mistake: When they are learning how to throw knives, the guy gets one thrown through his hand. If you watch this carefully, blood starts coming out of his hand before the knife hits. (00:28:45)
Revealing mistake: When the boys go into the bear cave and all of the snakes are hissing, you can clearly see that one of the snakes is a rubber snake with a black stick attached to its head - the black stick is coming from a whole in the ground. It is not even a good snake, the 97 cent 'convenience store' variety.
Revealing mistake: After Dante's Peak explodes for the final time, the pyroclastic cloud rolls down the mountain toward the town. Harry shouts "Don't look back, kids, don't look back." and then we are shown a wide shot of the truck zooming down the ash-choked streets. Unfortunately, it's painfully obvious that this is either a miniature or CGI shot, because the truck isn't leaving any tracks behind it or trailing any clouds of ash despite its high speed. (01:28:19)
Revealing mistake: Wait until the end of the bonus footage of the Spice Girls' live performance of "Mama". At the very end of the song, the music and voices fade out. Sporty appears to throw her body and soul into one of the lyrics, even though the lyric is barely audible because of the fadeout. It actually looks pretty funny.
Revealing mistake: When Nick is being followed by the PI, several times Nick's speedometer is seen to be at zero. (00:58:40)
Revealing mistake: When the needle is set in the pool of water in a stump to act as a compass the pool has been carved out with a chain saw very recently and clumps of the wrong moss set around the rim like it belonged there.
Revealing mistake: Near the end of the film, when Dacascos is fighting that other guy from Hong Kong, if you watch just after he does this smart kick, the guy's actually an Asian stunt double, and a lot shorter than Dacascos (best seen on the DVD putting it in slow motion just before).
Revealing mistake: When the Rangers arrive in the cave entrance of Maligore's temple (as Tommy cries "all right guys, this is it!") watch to the right of the screen, as Justin (the Blue Ranger) puts his arm against the stone cave wall and it wobbles, revealing it is a fake set wall. (01:11:40)
