Stand (Up) and Deliver - S1-E17
Character mistake: In one scene Brenda refers to Brandon's political opponent as "Michael Miller" but a few scenes later David refers to the same guy as "Robert." He's referred to as Robert for the remainder of the episode.
Continuity mistake: When Dylan pulls up to the After Dark, a group of guys come over and ogle his car, but when Dylan enters the club, one of the guys outside is already at the bar. (00:11:15 - 00:11:50)
Steve Sanders: Girls mature faster than guys.
Brandon Walsh: Not in my house they don't.
Question: In the first few episodes, the Walshes live in a different house than the one they live in throughout the series. Nothing was ever even mentioned, I don't think. Was it a mistake, or did I miss the explanation?
Answer: There was no explanation. Usually, when a show doesn't know if it's going to be picked up or not, they will use stock footage until they can spend the money on a real location.
