Beverly Hills, 90210/Trivia
- Actor Allusion:
- Maeve Quinlan as the mother of a girl who dates another girl.
- In one episode, Dixon is given a fake ID with a Spanish name on it. Tristan Wilds is Hispanic.
- The Danza: Ryan Matthews is played by Ryan Eggold.
- Riley is played by Riley Smith.
- Dawson Casting: In the extreme, to the point where this trope is often called "90210 Syndrome" outside of this wiki, since the extremeness makes Dawson's Creek look like they cast age-appropriately.
- Though there were some aversions (Brian Austin Green, Tori Spelling and a few others), the straight examples were very extreme (most infamous was Gabrielle Carteris who was twenty-nine when she started on the show).
- Teddy Montgomery is 17 or 18. His actor, Trevor Donovan, is 31.
- Dye Hard: Silver is a natural blonde as shown in the parent shown, but is a brunette for the entirety of the series save for when she briefly dyed it red.
- Executive Meddling: Season Two drops Ethan and focuses a lot more on the new characters rather than the old cast. That's cleverly done for Kelly's mother's funeral as it's not shown and Silver comments that a lot of people that knew her but she didn't know attended.
- Fake American: Shenae Grimes is Canadian.
- Fake Nationality: Michael Steger is a mix of several nationalities but Iranian (or anything Arabic) is not one of them.
- Hey, It's That Guy!: It seems Michael from The Wire did get a lucky break after all.
- Annie was Darcy on Degrassi.
- Debbie was Aunt Becky in Full House.
- Ashley Davies as Gia's ex.
- Paula Carlin as Adriann's mom.
- Plus Aiden plays Jeremy.
- Amy Bradshaw as Naomi's evil sister.
- Ethan Whitehorse as Ivy's British friend.
- Tyler Lockwood made Naomi kiss Annie.
- Billy Ray Cyrus as Austin's dad.
- Julie Taylor as Rhonda.
- The Other Darrin: Rather than bringing back Mercedes Castner to play Silver, she was played by Jessica Stroup.
- Unintentional Period Piece: This was the first of the many, many iconic teen dramas of The Nineties, and the first of many to fall into this trope. It also does a great job at keeping up with the times. Season One looks straight out of the 80s while Season Five and later look straight up 90s.
