The Case of the Sausalito Sunrise - S9-E19
Revealing mistake: Secretary Della Street answers the telephone in Perry's office and speaks briefly with the owner of an art gallery. She presses the "hold" button, then hands the receiver to Perry and says, "It's Mr. Clune." Perry and Mr. Clune have a lengthy phone conversation, even though Della never released the "hold" button.
The Case of the Sausalito Sunrise - S9-E19
Other mistake: The owner of a Los Angeles trucking company tells a driver who is going to San Francisco, "Take the San Diego Freeway toward Bakersfield." That freeway runs from San Diego to San Fernando. It does not go toward Bakersfield.
The Case of the Runaway Racer - S9-E10
Other mistake: Pete Griston is test-driving a race car. When the car stalls, another driver crashes into him. Pete is thrown from the car and suffers a head injury. Several scenes show him with a huge bandage on the back of his head. His hair was not shaved. The bandage is on his hair.
The Case of the Fanciful Frail - S9-E24
Other mistake: Park Milgrave finds a small chest full of realistic counterfeit money in Bruce Strickland's apartment. (Counterfeit money was not used for this scene. The chest actually contained three stacks of dollar-sized paper with a real bill on the top of each one.) Milgrave dumps the money into a metal urn and lights it on fire but the money he dumps out is play money, which does not look even remotely like real money.
The Case of the Laughing Lady - S9-E1
Continuity mistake: Professor Toby is shown in the background as someone in the audience is highlighted, but is supposed to be on the witness stand and appears there in the next instant.
The Case of the Cheating Chancellor - S9-E4
Character mistake: Paul Drake tells Perry the "speedometer mileage" of a murdered man's automobile is 63,192. Speedometers do not show mileage. He meant to say "odometer."
The Case of the 12th Wildcat - S9-E8
Other mistake: Perry, Paul and Della attend a Wildcats football game at the Los Angeles Memorial Coliseum. Stock footage shows a packed stadium. After the game ends, a close-up shows the three exiting the stadium along with several other people. The next scene takes place outside the entrance to the Coliseum. In a long shot, only two cars and six people are visible. In 1965, the Coliseum's seating capacity was 101,574. Where did everyone go?
