Before Nancy Drew got a contemporary TV show of her own on The CW, Archie Andrews and his friends got a dark Netflix drama, and the teenage residents of a town called Tree Hill started growing up, there was a successful teen show called Beverly Hills, 90210. While we would consider a series that lasts for a decade to be a massive accomplishment and not many get to that point, 90210 aired from 1990 until 2000, 90210 showed many people that a juicy teen drama was always going to attract viewers.

Leading to other reboots, such as the 2009 one starring Shenae Grimes-Beech and the recent revival BH90210 which only got one season, the brand has always been a strong and recognizable one. The original series made its young stars famous and a lot went on behind the scenes.

Keep reading to find out some of the interesting drama that took place while the actors were filming Beverly Hills, 90210.
