Other mistake: In the opening credits of Season 4 (the Tori episodes), when Leanna Creel is shown, the second of her three sequence shots is in reverse (where she is sitting at the Max in a red outfit in front of a candle). In the episode where that clip is from, she was sitting to the right of the table facing left, but in the opening sequence, she is on the left of it facing right (mirrored image).
Saved by the Bell (1989)
1 other mistake in season 4 - chronological order
Starring: Mario Lopez, Mark-Paul Gosselaar, Dustin Diamond, Lark Voorhies
Visible crew/equipment: After the fashion show when Zack says "Sorry Lisa, I don't know what to say" an entire boom microphone assembly is visible and snatched out of view at the top of the screen.
Lisa: Yeah, 'I have all these problems and there's no-one ever there for me. I talk and talk and talk but no-one ever listens.'.
Trivia: Of the main six characters, Screech is the only one whose father never made a physical appearance on the show.
Question: What happened to Kelly and Jessie in the episodes with Tori? Can someone explain what went on there.
Answer: As far as I can tell Jessie and Kelly decided to leave the show because their contracts were up and they wanted to pursue other things. But there were still episodes of Saved by the Bell left to tape so Tori came along to fill that void. Jessie and Kelly were supposedly still at Bayside, but they were "off-screen." The Graduation episode was filmed before Kelly and Jessie left the show.
