Goofs

There are 4 celebrity head shot pictures on the wall to the right of Nora Chandler's bar; the lower right picture of Nora changes with no explanation.

A blonde girl in gray dress climbs the same stairs twice during the conversation between Lt. Columbo and Mr. Fallon.

During the first scene in Jerry Parks's office, the photograph of Clark Gable disappears and reappears in different shots.

After Jean Davis parks at The Seekers book shop, she goes inside to meet Jerry Parks. Nora then gets out of a green Malibu and runs up to the store to see Jean and Jerry embrace inside. The large window she looks into has white wooden framing with a hedge underneath the sill. However, the previous and subsequent long shots of the façade show no white window and no hedge.

Exterior shots of Nora Chandler's bungalow, shot on the Universal back lot, show the front door with brass colored hardware knobs. The Interior set front door hardware is dark brown in color and does not match. The brick wall right outside the front door of the bungalow is closer on the interior set and much farther from the front doors on the exterior shots.

Pouring gasoline onto concrete would not make a fire capable of causing a car explosion. In fact the car explodes before the flames reach it.

When Columbo uses Nora's overwrought reproduction phone to call his wife, he not only dials just 5 numbers (distracted by continually talking to her), but afterwards, there is not enough of a time lapse for the connection to be made - in those days the process, which emitted audible sounds & took at least 5 seconds before the 1st phone ring - or for there to have been even 1 ring before "George" answered the call.

The Jaguar XKE was incinerated and its burned-out hulk was impounded by the police, yet its tires were unscathed.

When Columbo first calls his wife from Nora Chandler's home, he only dials five numbers (instead of seven).

In the opening scene, Nora Chandler fires her revolver into a glass shower door. Only with the first shot does the glass breaking almost coincide with the sound of the gunshot and muzzle flash. With the next 5 shots the reports and muzzle flashes coincide, but there are quite noticeable delays before the glass breaks. Further, sometimes the glass breaks where she is NOT pointing the gun.

As Columbo shows his police identification and badge to the studio gate security guard, a page of a script (most likely for that scene) is visible on the front passenger seat of the car.

When Nora is finished shooting the process shot in the studio, the shadow from the real camera crane can be seen in the lower left corner.

When Columbo first telephones his wife, the boom mic falls into view.

Columbo says he has never been in a movie studio before; however, he has, in the 'pilot' movie Prescription: Murder (1968). He could be lying here, though.
