When the candidate and his campaign manager get on the elevator, the car is crowded with both men having to stand at the front, by the doors. After the elevator falls to the basement and the doors are forced open, half the passengers are gone, with enough room for the remaining people to lie on the floor and not on top of anyone else.
When Kolchak presses the elevator button with another man also waiting, the button does not light up. In a later scene when he presses the elevator button, it lights up.
The first automobile explosion is supposedly driven by one of Palmer's rivals. But the vehicle is a 1930s roadster with spoked wheels, showing the use of antique footage.
During the attack in the park, eucalyptus trees are visible in the background, which do not grow in the Chicago area.
When Kolchak is viewing the two cars involved in the wreck, there is old rust visible on the damaged areas. The cars were damaged much longer than actually implied.
In the beginning of the show when the elevator is crashing, the internal button lights are going the wrong way.
In most U.S. elevators, the button numbers go upwards in increasing floor numbers.
If the elevator is descending, the button lights should have been in descending order as well, not ascending as shown.

During the end credits, Ruth McDevitt's character name is listed as "Edith Cowels" when in actuality she plays Miss Emily Cowels.
The story is taking place on multiple dates in August. When Kolchak is in the bar, the Chicago Cubs are playing the Boston Red Sox. In 1974, this would only take place if it were a World Series game, as the teams are in different leagues, which would place the game in October. This is actually recycled material from a previous episode, where Kolchak has to miss going to a World Series game due to a story he's working on.
In the intro, when various rivals of Palmer are killed, the second victim is described as sailing his yacht on Lake Michigan. Yet the yacht flies a French flag, not a U.S. flag.
No one is able to identify the dog in the show as being a Rottweiler. This exceptionally odd as they were common types pets even in the 1970s.
Ron says that no domesticated dogs have five toes, and that only wild African and Asian dogs have five toes. In fact, many domesticated dogs have five toes - including Shepherds, Rottweilers, Yorkshire Terriers, Poodles, Mastiffs and Saint Bernards. The adaptation is generally environmental in rough terrain, as the fifth toe provides extra traction.
