Goofs

As seen from the train depot, the house where the assassins are hiding is way up on a hill, well back from and high above the station, but as seen in shots looking down at the depot from the window in the house, the depot is only slightly higher than the house, and so close as to be almost next to it.

The TV repair man is listed in the credits as "Jud Hudson," but when asked his name when he arrives to fix the TV, he says his name is "Jud Kelly."

When Pidge swaps guns, the Schick electric shaver in the drawer changes positions in different camera angles.

When Sheriff Shaw is making the phone call from the railway station, the mouthpiece jumps between an upper and a lower position in the long and close-up shots.

When Tod is informed of the emergency message, in the shot through the sheriff's office door Tod's tie is blown up over his left shoulder. In the cut to outside the sheriff's office, the tie is down.

When Baron's henchman touches the metal table grounded to the television set, he is standing in water deliberately spilled on the floor by Pop Benson for that purpose and, according to the script, electrocuted, but the camera shot of his feet shows he is wearing rubber soled shoes. So he could not have completed the circuit.

Unless the water on the floor had a ground wire or leaked to a radiator, etc, the table and rifle would have 5,000 VAC but not ground to connect a circuit. So He would not feel anything. And if it did, his muscles would freeze up and not make him pull the trigger repeatably.

After Baron shoots Shaw and Agent Carney, he goes to the window and says that the train passing muffled the gunshots. However, there are no train noises until after the shots.

At the end of the film, after Ellen tells Tod that she'll pick him up after church, she gets in her car and pulls away from the curb with no regard for the guy in the oncoming Buick a mere few yards away.

The TV repairman (Jud Kelly) is not listed in the credits as Jud Hudson, but Jud Hobson.

The train is going north (the afternoon sun is streaming across the tracks into the train station from the direction of the house), yet the audio says the train is going down to Los Angeles, instead of up to San Francisco. If time of day were incidental to the film, this would be overlooked, but the clock is the tension builder.

With the rifle locked in place, the chance of the President being exactly in line of fire is slim to none.

The Secret Service would never allow the train to stop without the head agent, who was killed, be present to coordinate the full operation.

After a member of the assassination squad was shocked and fired the rifle multitude of times, the agents would immediately kill the stopping of the train.

When Pidge starts taunting the assassins, it's from Benny he first gets a rise, but Baron stops Benny from roughing up the kid. A minute later, it's Baron that gets riled and Benny acts the peacekeeper.
