Starring: Raymond Burr, Barbara Hale, Ray Collins, William Hopper
The Case of the Silent Partner - S1-E6
Other mistake: A police officer sees a fire burning inside the home of Lola Florey and calls the fire department. The ground is dry. Stock footage shows three fire trucks speeding toward the scene, and the streets are wet.
The Case of the Wayward Wife - S3-E13
Revealing mistake: Perry and Della step into an elevator but there is no line in the floor between the floor they are on and the elevator floor. It's continuous.
Hamilton Burger: Incompetent, irrelevant, and immaterial.
