It is supposed to be a stormy afternoon, yet there is clearly bright sunshine and clear blue skies when Steve is running through the woods near the cabin.
Steve crashes his car during dusk, yet it is bright daylight as the ambulance rushes him to the hospital.
In the outdoor shot of the OSI building just before Oscar discusses with Steve about his recent experiences with the lady doctor and the driverless car, the weather is mild and clear, yet in the shot of Steve standing by the window while he's conversing with Oscar, it is clearly raining outside.
Steve's car screeches to a halt a good distance from the doctor's house, yet the car is later seen sitting just a few strides from the doctor's front door when she runs to where Steve has bionically stopped the car.
In the opening scene, Steve's car radio announced a hurricane that had ravaged the West Coast of the U.S. and Mexico. Hurricanes do not hit that coast.
Since it's determined that the Russians planned the entire scheme to confuse and capture Steve Austin, there is never an explanation why a highly renowned parapsychologist recommended by Rudy Wells, would try to kill Steve with a fireplace poker.
Crouching stunt driver visible inside Steve's "driverless" car.
Just before Steve enters the cabin, the lightning bolt clip starts to transition to another scene from the movie the lightning was taken from. You can see a road and car appear in the clouds for just a moment.
Obviously clean-cut rope ends after Steve "bionically breaks" the ropes holding his lady-doctor friend.
Obvious use of a smoke machine --- the blast originates outside the lady doctor's hallway entrance, and there is very little smoke inside the room, yet in the shots of Steve checking the outside doors and then carrying the doctor out through them, there is much thicker smoke near the back doors, and several very visible large puffs of freshly-generated smoke near the floor just inside the doors.
Obviously clean-cut (chainsaw-made) stump-ends of limbs in the brush-pile that the lightning-hit tree falls in front of, even though this is supposed to be a "way out in the willywags" location in deep forest.
When Steve is fighting with the villains in the cabin, the bionic sound is heard when he shoves a guy with his left arm, even though it's his right arm that's bionic.
The driverless car's engine can still be heard after Steve bionically halts it, yet the ignition key is clearly in the OFF position, and the idling sound stops when Steve takes out the key.
The sound effect of Steve descending from the jump out of Margaret's office window starts a few seconds before Steve makes the leap.
Someone in a similarly-colored jacket (possibly Steve's stunt-double) can be seen standing at the edge of the woods as Steve runs past a huge obscuring tree trunk when he starts following the station wagon.
The still-venting bottle of poison gas is sitting on the ground a short distance outside the doorway of the mercs' cabin, and the already-expended gas inside the cabin would be seeping out of the open doorway, as well, and so Steve would not have stopped on the porch to talk to his friend; he would have moved farther away so that they would not breathe any more of the gas.
The police car does not turn on its blue lights as it stops to help Steve when he's wrecked his car, even though the siren is going. Except during undercover work, officers **always** turn on their lights whenever they think there may be a hazard or injured person nearby.
