This is one of the few episodes of Columbo (1971) in which 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 »


Columbo: That's right, Doctor. That man that you saw was blind... and is blind. This is Daniel Morris. That's the man that you saw on the road Monday afternoon. This other man is his brother, David. I'm sure you can see the problem, sir. There is no way in the world that you could've assumed that this man, this witness was blind unless, of course, you had seen this man that day. That's the only way you could've known. Thank you.
David Morris: You're welcome.

George Hamilton as the slickest of villains
5 September 2016 | by See all my reviews

A DEADLY STATE OF MIND is one of the best Columbo episodes I've watched. It's a story that never puts a foot wrong, packed with engaging and enjoyable performances and a wonderfully twisty plot with some great surprises hidden along the way. George Hamilton plays a delightfully suave hypnotist who accidentally murders a love rival in the opening scenes and decides to cover up the crime as best he can.

Unfortunately for him, Columbo is soon on the case and sniffing out some of those delightfully insignificant clues that become important later on in the game. What follows is a cat and mouse story in which the stakes are gradually raised to breaking point. There's a wonderful swimming pool set piece and great acting from supporting starlet Lesley Ann Warren, who makes the most of her conflicted and fragile character. Hamilton gives a performance that reminded me of Roger Moore, all bluff and bluster and raised eyebrows; he's great fun. And of course, Peter Falk excels as Columbo in one of his most likable appearances as the detective. Plus, A DEADLY STATE OF MIND incorporates one of the best twist endings I've seen in any Columbo film.
