Beverly Hills, 90210 (1990)

Show generally

Other mistake: When the show aired in 1990, in the pilot episode Brenda falls for Jason. She later on reveals herself to be a "16 year old junior" in high school. Season 2 opens up with the gang on summer break which technically would make them going into their senior year. It wasn't until Season 3 that they were going into their senior year. They graduated in 1993 from West Beverly but the show debuted in 1990 so technically they should have been sophomores.

Brandon Walsh: It was good to see you back at the Peach Pit tonight. I know it took a lot of courage.
Brenda Walsh: Brandon, please, I've had quite enough praise for a while.
Brandon Walsh: All right, you're a huge loser. How's that?
Brenda Walsh: Oh, much better.

Fade In, Fade Out - S6-E17

Trivia: At the Peach Pit After Dark, Steve and the gang screen the film Unholy Rollers (1972), in which Nat appears. Joe E. Tata, who plays Nat, actually had a supporting role in that film.

Season 1 generally

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?
