When the final enemy missile is launched, it leaves the silo as a Sprint but becomes a V-2/A-4 in flight. The Intercepting missile launches as a Nike Hercules but becomes a Hawk missile in flight. The final intercept shows not a missile being destroyed but a T-33 target drone.
When Jamie is bending the pole for the outside laser the laser is pointing toward the sky, when Mr. Connors comes to look the laser is pointed toward the ground.
When Jaime first uncovers the buried electrical junction box, it is a shiny coppery color, yet in the closeup shot of the top of the box, it is just a dull leaden-gray hue.
The metal signpost with a cement base that Jaime throws at the radar-jamming antenna repeatedly changes back and forth from a post with the sign still attached to just a plain post without the sign; this scene also re-uses some of the post-removing and throwing footage from one or two previous SMDM movies, where the cement base is a rough irregular-textured pear-shaped blob instead of a fairly even-dimensioned smooth-surfaced cylindrical plug.
It is night when Jaime breaks into the secret building on Mr. Connors' property, yet in the shots of Mr. Connors sitting at his desk before the intruder alarm is raised, the room is bathed in bright sunshine.
After Jaime breaks the padlock off the door, she does not pull out a movable handle or anything else that the padlock would have been securing from being actuated; she merely pulls the door open, without unlatching anything. The entire handle-assembly --- including both of the circular metal ring-staples that the padlock was threaded through --- swings out along with the door, so the padlock was obviously not "locking" any part of the door-handle onto a corresponding rigid part of the outer door-frame; the padlock was just hooked into a non-moving part of the handle-mechanism. The door's latch is obviously fake, also, since it has no noticeable protruding plunger to fit into a pocket in the door-frame and keep the door closed; it appears to be just a simple ball-and-spring latch, like on a medicine-vanity door in a washroom.
J.T. states that the yellow locomotive's bell is hooked up to a remote-controlled actuator, yet the bell's ringer-arm is clearly not connected to anything. Obviously the arm's actuator-linkage was disconnected to permit the bell to freely swivel back and forth, and thus allow someone hidden on the other side of the engine's boiler to swing the bell by hand.
The bionics shown on Jaime's damaged leg at around 17:40 are totally different to the damage shown at around 34:40.
Steve says he has a target on his radar scope, yet the scope has no blips on it.
As Jamie is getting ready to throw the signpost at the antenna her arm is too low, all she would have done is hit herself in the back of the head with the sign.
When Oscar gets out of the helicopter to pay the ransom the briefcase he is carrying is too small to hold 15 million dollars.
It's The Nanny syndrome! And a recurring one in this show: Jaimie is talking to the old guy, wearing 2 sweaters in a gorgeous shade of red that brightens her up. They move to the next room and---for no valid reason whatsoever---Jaimie has changed her clothes and is now wearing a dull black and white outfit with a geometrical beige pattern in the front. The old guy still wears the same clothes.
