Most Donna Reed Show fans already know that Seasons 4, 6, 7 were pulled from the syndication (or rerun) package in the early to mid 1980s. However, these episodes were not pulled by the season in which they aired...they were pulled by the season in which they were
filmed.
At the end of each filming season, there were usually two episodes ready to go for the next season. For example, the first two episodes of Season 3 ("Weekend" and "The Mystery Woman") were filmed at the end of Season 2. (You'll notice that Donna's hairstyle and Shelley's hairstyle change in the third episode of Season 3, "Donna Decorates").
Seasons 1, 2, 3, 5, and 8 aired in the 1980s syndication package which aired on Nick-at-Nite. There were two Season 4 episodes that actually aired during the Nick-at-Nite run: "A Rose is a Rose" and "The Mouse at Play". This is because they were filmed at the end of Season 3 and were counted as Season 3.
All episodes
filmed during Season 4 were pulled from the syndication package, which includes, "Mister Nice Guy"; which filmed at the end of Season 4, but aired as the first episode of Season 5. When Season 5 aired on Nick-at-Nite, we didn't see this episode, because it filmed during Season 4 and was counted as Season 4 (and episodes filmed during Season 4 were pulled from the syndication package). So when Season 5 is released on DVD, everyone will get to see an episode that hasn't been seen in years (the first episode of Season 5, "Mr. Nice Guy").
In the Season 6 episode, "What Are Friends For", some people think Shelley returned to the show for this episode (even though she is only seen for a minute). However, this episode was filmed at the end of Season 5, but aired as the 11th episode of Season 6. Even though this episode is Season 6, it aired on Nick-at-Nite, because it was filmed during Season 5 and was counted as Season 5.
Everything filmed during Season 6 and Season 7 was pulled from the syndication package.
A total of 99 episodes were pulled from the syndication package (37 episodes from Season 4; 1 episode from Season 5; 31 episodes from Season 6; 30 episodes from Season 7).
I have copies of original Screen Gems lists that show these filming and air dates. I also taped all the episodes when they aired on Nick-at-Nite. What Nick-at-Nite aired matches what I have listed above.
