Starring: Lorne Greene, Michael Landon, Pernell Roberts, Dan Blocker
Revealing mistake: Jack Albertson's character is taking pictures of The Cartwrights and ranch hands. The video camera moves across the front of the prop camera as Albertson pushes and holds the button to take a picture. The shutter on the camera never opens and isn't open until he releases the button. In those days the shutter had to stay open an elongated time to enable the light to infiltrate the negative. People had to stay still during this time.
