Corrected entry: Nile's opens the door for CeCe. She walks into the room where everyone is sitting. Behind her you see someone hidden by the wall and then run across the hall opening.
Corrected entry: In the Christmas Episode (s1e8), we are told Fran's watch meant a lot to her because her grandmother gave it to her on her deathbed. In this episode Fran has two living grandmothers.
Correction: Fran's bubbe (Yiddish for grandmother) Sophie is dead though, this is mostly likely a reference to her.
Who is Sophie? Fran's Grandmas are Nettie Fine and Yetta Rosenberg. Both are alive.
Bubbie Sophie is mentioned in S4xE4 The Rosie Show. She's portrayed in the dream cemetery sequence by Fran Drescher. I believe that Bubbie Sophie is meant to be Yetta's mother, so Fran's great-grandmother, and she may have died right before Fran was born, or when Fran was a baby.
Continuity mistake: Fran's belt changes when she is in the kitchen from a pink leather one to a zebra one and then back to the original.
Suggested correction: As soon as it cuts from the show's intro to the first shot in the kitchen, we see Fran buckling her old zebra-striped belt around her waist. When Niles picks up the artificial lemon tree we see Fran touching her belt, and as the camera faces Niles when he exits the kitchen Fran unbuckles her belt offscreen. In the next shot Fran's zebra-striped belt is in her hand, and she places it back in the box of her old stuff from her Ma's house. No continuity issue. Starting time code 00:03:35.
The Pre-nup - S5-E20
Continuity mistake: In the scene where Val and Fran are in the kitchen, Fran jiggles her tea bag, the removes it and places it on the napkin beside her. Brighton enters and after a brief conversation Fran returns to the table carrying cream and sugar. She then jiggles and removes the teabag from her cup again. (00:07:00)
Suggested correction: Fran is in the kitchen with her mother, not Val.
Correction: It is Maggie who is walking back there.
Bowling255 ★
Bowling 255 is correct. I went back and rewatched this scene and it is indeed Maggie in her peach shirt and plaid pants. She hesitates as she walks out, so it does look like an accident. She steps back and then walks out again, but the scene cuts to her already standing by the stairs. So this is actually a continuity error.
