Goofs

Columbo has shorter hair when talking to Arthur Kennicutt by the pool than when, after walking into the house, he meets Brimmer.

When Brimmer, seated at his desk, is writing the receipt for Columbo, he's writing on the folder cover in the first shot. In the second shot, he's writing on a receipt pad.

At the beginning, Mrs. Kennicut is in the back office listening to the meeting in the outer office. There is a pencil cup with pencils in it on the desk blotter right next to the speaker that is also on the blotter. After the meeting, when Brimmer enters the back office, the speaker is off the blotter, and the pencil cup is in a different place on the desk, far from the speaker.

When Brimmer, seated at his desk, says "crystal ball", he holds his coffee cup in his right hand. The camera cuts to Columbo for three seconds, and when the scene switches back to Brimmer, the cup is now in his left hand, while his right arm rests over on the arm of his chair. A moment later, when Columbo gets up from his chair, the cup is back in Brimmer's right hand, as he transfers it to his left.

As Brimmer chews out Denning, Denning puts his hands in his pockets, but when the scene cuts to a room shot, Denning's hands are behind his back.

Columbo is pulled over by a motorcycle cop because he has a tail light out. When Columbo tells him that he is a detective on his way to investigate a murder, the cop tells him that he will give him an escort so that he won't be pulled over again. The cop gets out in front of Columbo and leads him to where the body is located, but Columbo hadn't told him the address where he is going.

After Columbo tells the officer, who is standing next to the car, to not go too fast, the scene cuts to both of them driving away, meaning that some time had passed that was not shown, during which Columbo had told him the address, but which the film makers chose not to share with the viewer.

When Brimmer drops the body, his car leaves clear track marks in the dirt. Columbo simply could have compared tire marks to know that Brimmer was at the location where the body was dropped.

One of the officers specifically stated that there were "no usable tire tracks". There could be a myriad of reasons for this, but it was stated at the scene of the crime and can be surmised to be the reason for the police not using that avenue of inquiry in the case.

After Brimmer dumps the body and drives away, he leaves fresh tire tracks that would solve the case easily by checking those tire marks to his tires.

No one present in Brimmer's indoor shooting range is wearing ear protection. A single shot from their revolvers could cause acute pain and momentary hearing loss to the shooters as well to the observers.

Near the beginning, Brimmer is shown driving his black Cadillac Eldorado at night with the body of Lenore Kennicutt in the trunk. For three seconds, a shot of Lee Grant from Ransom for a Dead Man (1971) driving a green Lincoln Continental is shown, then the film cuts back to Brimmer.

Brimmer drives forward into the area where he dumps the body. As he drives away, his fresh tire tracks in the fine silt/dirt are visible, yet where the fresh tracks his tires would have made upon entering the scene, the silt/dirt is undisturbed.

After he dumps Lenore's body, Brimmer drives his car away, leaving tire tracks in the dirt. The next scene shows a cadre of vehicles--EMTs, an ambulance, and cop cars in that same area. They clearly have disturbed the scene of the crime--analysis of the tire tracks Brimmer's vehicle left behind could have been used to help track him down.

At 19 minutes and 14 seconds, the heavy blanket, covering the corpse of Mrs. Kennicut can be seem to move abruptly. It is clear there is no wind and no one has bumped into the stretcher.

(at around 17 mins) As Columbo pulls away in his car, there are shadows of the camera and at least three crew members visible on the ground.

Mic is visible when Columbo first sees the body.

When Bremmer gets into Kennicutt's car at the cemetery, you can see the microphone cord sticking out at his waistline.

Brimmer states that around 10% of the world's population is ambidextrous. In fact, it's about 1%; about 10% is left-handed.

Brimmer incorrectly says "specie" as a singular form of "species". The singular of "species" is "species".

After Brimmer comes into his house, he crosses his living room, then turns back to find Lenore there, to his surprise. He should have known she was there because she then reaches forward to an ashtray in the middle of the room and removes her lit cigarette. He should have smelled it as soon as he opened the door, and he nearly walked right past it.
