Diamond Jack - S7-E3
Revealing mistake: As Terri exits Jack's bedroom to stall the diamond thieves, you can momentarily see into the girls' bedroom. The wall that should be between the girls' bedroom and Jack's bedroom is missing and the floor and blue curtains of Jack's bedroom set are visible. Someone's arm wearing a light colored shirt (John Ritter's sleeve is brown and Joyce DeWitt's sleeve is black) can also be seen moving. (00:25:00)
Continuity mistake: When Mr. Roper tries to explain to the girls and his wife what he was doing in Jack's bedroom, watch over Mr. Roper's left shoulder on the shelf. The number of yellow cans on the shelf keep alternating between one and two cans throughout several minutes. In addition, also notice the suitcase on the floor under the shelf as well. Whenever one yellow can is shown, the suitcase is by itself and whenever two yellow cans are shown, there is a square silver bag in front of the suitcase.
Jack Tripper: And speaking of current events, did you read the big news in the paper this morning?
Chrissy: The May Company is having a huge sale on pantyhose.
Jack Tripper: Excuse me, Chrissy, that's not exactly a current event.
Chrissy: It is so, it's going on right now.
Trivia: Once the first season with Terri started, Cindy no longer had "Snow" mentioned as her last name for the remainder of the episodes she was in (possibly due to the fact that this was the first season that started without Suzanne Somers completely and the producers wanted to retire the "Snow" surname altogether).
Question: During the first three seasons, all the main cast appeared in every episode (except one without Joyce Dewitt by season 3), but it seems once Suzanne Somers left the show, episodes had some cast members absent on a regular basis (mainly Richard Kline and Don Knotts who both only appeared in selected episodes in the later seasons). Was it a sudden budget cut or another reason for this?
Answer: Richard Kline and Don Knotts were supporting cast members, who could be replaced at anytime. It was John Ritter, Joyce DeWitt and Suzanne Somers who were the star vehicles they relied on to carry the show.
