Starring: John Goodman, Laurie Metcalf, Johnny Galecki, Sarah Chalke, Roseanne Barr, Michael Fishman
Home for the Holidays - S9-E12
Revealing mistake: When the family is eating the Christmas cookies, look at the top of the screen. In the kitchen, you can blatantly see where the top of the kitchen actually ends, revealing gray panels. The Conner's ceiling never went up this high, so it is definitely set material.
Halloween - The Final Chapter - S8-E5
Continuity mistake: Roseanne becomes pregnant at the beginning of Season 7, and it is before the Halloween and Thanksgiving episodes, so she is in her first trimester during the holidays. However, Roseanne does not give birth until the following year in the Season 8 Halloween episode. Her pregnancy has lasted for well over a year.
Trivia: Shelley Winters plays Estelle Parsons' mother in the series, even though in real life she's only seven years older than Parsons.
Question: Was Sara Gilbert (Darlene) pregnant in real life when she was pregnant on the show?
Answer: No. Sara Gilbert has given birth to one child (so far) and that was in 2007.
