Revealing mistake: When Smoke is running up to Kitana at the start of the Liu VS Smoke fight, Liu runs up behind him, jumps and pushes his foot against a pillar to sort of rebound, and grabs Smoke. There's a quick insert shot of Liu's foot pushing against the pillar, and you can see the "stone" pillar briefly bend like rubber beneath his foot, revealing it's fake.

Revealing mistake: Watch closely when Scorpion breathes fire at the end of his fight with Johnny Cage. In the wide profile shot where we see the "stream" of fire shooting out and hitting Johnny's shield, if you look very closely, you can kind of make out some sort-of "structure" within the flame. It looks kind of like a pole. It looks like to accomplish the effect, they lit a "flame bar" or pole on fire so the flames would travel upwards, then comped it into the scene and rotated it using special effects to make the flames look like they were shooting sideways. Unfortunately, the pole/flame bar is still just barely visible in the film. (It's much easier to see on the Blu-Ray version, but can be made out on the DVD).

Revealing mistake: During the big chase, watch closely when the car goes over the ramp and does a flip. As soon as it lands, you can catch a brief glimpse of a partially-destroyed film camera (covered in black material) rolling along the ground. Its position on the road lines up with one of the previous shots, so it's definitely a camera. (It looks like the car landed on it and threw it along the ground).

TedStixon

Revealing mistake: During the Jax vs Cyrax fight, pay attention right after Jax says "Yeah, now what?!" A few shots later, Sonya is hit in the face with a weapon by one of the extermination squad members. But you can see plain as day that the weapon completely misses her. It actually goes over her head, but she still reacts as though she's been hit in the face.

TedStixon

Revealing mistake: During the Liu VS Baraka fight, pay attention when Liu and the Barakas are swinging around on the chains. Several times, you can see safety-wires attached to the chains and actors. It can be hard to catch, but there are at least three or four shots where they are visible.

TedStixon

Revealing mistake: When Sheeva is crushed by the cage, pay attention to the first shot as we see the cage falling towards her. You can see the cage actually come to a stop right before it cuts to the low-angle shot looking up at her screaming. (Since it would be rigged to stop above the actress so it wouldn't actually crush her. They unfortunately just cut the shot too late).

TedStixon

Revealing mistake: In the burning barn, watch closely when Zorro goes to jump on the horse. There's a low angle shot of his feet running up to the horse, and a piece of burning wood lands in the foreground. The fire on top of the burning wood is burning upwards like normal fire. However, the fire on the side of the board is somehow burning upside-down, with the fire moving downwards. Seems to be a slip-up in the digitally-added fire effect. It goes by quick, so slow-motion helps, but is not required.

TedStixon

Revealing mistake: Watch closely when Zorro's horse bursts into the burning barn. The visual effect is comical. It, along with some debris in the air, simply appears between frames in an unrealistic way.

TedStixon

Revealing mistake: In a few of the wider crowd shots during the pod-race, you can make out some oddities. In particular, if you look closely, you'll see the same group people copy/pasted over and over in different places and different configurations in the audience to make the crowds seem bigger. (Slow motion or pausing helps, but is not necessary.) This is actually a relatively common special effects trick to make crowds seem bigger.

Revealing mistake: When Will's wife shoots Dollarhyde at the end, watch closely when she shoots him for a second time and hits him in the cheek. For about one frame, you can see what looks like a wire coming out of his cheek that has caught some light, and about a half-second later, you can see some sort-of small brownish cap hit the floor on the right side of the screen. (It's very tiny so you have to look closely.) These types of effects are usually accomplished by putting a small prosthetic cap attached to a piece of wire over the bullet wound makeup, which is then pulled from off-screen to reveal the "bullet hole." It looks like both the wire and prosthetic cap both managed to get caught in the shot. (Slow motion or freeze-framing help but aren't required - both the wire and the cap are easy to catch once you see them the first time).

TedStixon

Revealing mistake: When Rayden and Kahn fight at the start of the film, at one point Rayden does a flying body-spear into Kahn, which sends him flying backwards. When he lands on the ground, the floor beneath him "warbles," revealing he landed on a pad. It also continues to move a bit for the rest of the shot as he moves.

TedStixon

Revealing mistake: When the Emperor's generals are introduced at the start of the film, pay attention to Sheeva's lower arms. If you look closely, her lower arms are added digitally and don't quite blend with the actress, nor do they 100% match her motion. (Especially her lower-right arm, which is on the left hand side of the screen. You can see it "clipping" with the background plate. At one point, it even briefly looks like it's floating behind her for a moment instead of being attached to her).

TedStixon

Revealing mistake: Jax and Sonya jumping away from the explosion when Cyrax self-destructs is just comical. The lighting on their bodies doesn't match the lighting in the background, revealing they were just filmed on a green-screen, and the background makes no sense whatsoever. The background is a blurry still image that doesn't have the same color-temperature as the exterior of the base seen earlier, with an obvious stock-explosion effect added over top of it that doesn't blend properly into the scene.

TedStixon

Revealing mistake: During the Jax vs Cyrax fight, at one point Jax gets knocked down to his knee, and then Cyrax kicks him, causing him to fly upwards and backwards and roll over the top of the metal gurney. Except you can see plain as day that Cyrax's kick completely misses Jax. He kicks his leg about two feet in front of Jax's head.

TedStixon

Revealing mistake: When Sonya is facing the "extermination squad" while Jax fights Cyrax, watch closely. At one point, a ninja clad all in black does a jump-kick, which knocks Sonya back. Except if you look closely, he doesn't actually kick her. (It's really obvious when the camera cuts to a side-view and you can see he doesn't have his leg extended.) But they still add in a kicking sound and have Sonya react as though she's been kicked.

TedStixon

Revealing mistake: During the Scorpion vs Sub-Zero fight, after the ice-bridge collapses, when Sub-Zero jumps down to the lower level of the stone bridge to face his foe, you can see the floor beneath him ungulate as he lands, revealing there's a pad beneath the snow.

TedStixon

Revealing mistake: Cyras appears, who launches two spherical bombs that attach to the walls and explode. Watch very closely. There is a low angle shot pointed towards a doorway right after they explode, and you can see the set wall visible shake for a brief instant from the pyrotechnics. It can be hard to catch, but once you see it, it's very obvious.

TedStixon

Revealing mistake: When Scorpion explodes, if you pay attention, the explosion doesn't really make "sense." The first "burst" looks fine, but then, midway through the shot, some of the debris in the air suddenly vanishes or fades out a few frames before the second "burst" occurs. Additionally, the way the second "burst" happens gives it away as an added effect, as it doesn't really overlap the background properly. (It looks like an explosion that was filmed on a blue-screen and then just added over top of the footage, as it doesn't interact with the environment properly).

TedStixon

Revealing mistake: When the scarab beetles surround Benni at the end of the film, watch closely... you can see many scarab beetles running directly "through" each other, revealing they are just a digital effect. (This is also visible in other scenes with the beetles, but it's most obvious in this scene, particularly in the first shot when the beetles begin to swarm towards Benni).

TedStixon

Revealing mistake: There is a mistake in the (quite dodgy) CGI when the car tumbles down into the dam in the opening scene. At one point, the camera cuts and we can see the car bouncing downwards through the air, and there's a splash of water from where the car bounced off the wall of the dam. But if you pay attention, the splash of water simply vanishes/fades away about two seconds later. Sure, if it was more of a fine mist, it'd make sense that it'd lose visibility, but these were huge streaks of water that should still be visible for quite a bit longer.
