Did You Know?


This is one of the few Columbo episodes where the original murder is a spontaneous act. In most episodes the murder is carefully planned. See more »


When Columbo is talking to Dr. Collier in the computer room, Columbo's arms are in different positions depending on the angle of the shot. When seen from the front, both of his arms are lowered, but when the camera angle changes so we are looking at Columbo from his rear right side, his left arm is laying across his stomach and his right arm is bent at the elbow with his hand up by his chin. This happens about 3 separate times during camera angle changes. See more »


David Morris: Always pack a bulky sweater and some heavy underwear. Even in the spring, the mountains can get pretty cold at night.

3 June 2012 | by (Buffalo, New York) – See all my reviews

In a lot of Columbo episodes you can feel sorry for the perpetrator, sometimes they're driven to kill and the one who died probably should have. Other episodes show a carefully planned scheme gone awry because of the way Peter Falk digs for clues. But this one was spontaneous as it gets. Husband Stephen Elliott catches his psychiatrist colleague George Hamilton with his wife Lesley Ann Warren and Hamilton kills him in the struggle.

Hamilton was one of the most hateful perpetrators ever in the Columbo series. Being a psychiatrist and knowing how the human mind works, he prepares a careful scenario about a home invasion and it looks pretty good. But an extremely tiny piece of evidence convinces Falk otherwise and also Warren begins to fall apart.

However what Hamilton does to cover up after this is where his true worthlessness of a human being is shown. You will stand up and cheer when Falk nails him and how he nails him.

Got to love that Lieutenant Columbo.
