90210 (TV series)
On January 13, 2013, the President of The CW Mark Pedowitz stated that though 90210 doesn't have a season 6 renewal in place, the show would most likely be back next year (possibly for the final season if it were to be canceled) due to him being a "big believer in giving fans a very satisfactory conclusion" for a long-running show. However, on February 28, 2013 The CW Entertainment President, Mark Pedowitz, announced that 90210 would end its run after five seasons and 114 episodes.

The producers wanted to see "as many of the original cast members as possible", but were careful not to "parade them all out in the pilot". Following rumors of cast members from "Beverly Hills, 90210" appearing on the spin-off, The CW confirmed that Shannen Doherty would be returning in a recurring role as her original character. Sachs met with Doherty over dinner, and told her about the "90210" spin-off. Over the next few weeks, they established Brenda's backstory and Doherty agreed to guest star in several episodes. Doherty and Garth told reporters that they were nervous about reuniting and filming scenes together for the "90210" spin-off. While starring in the original series, the actresses were known for feuding on and off the set, which lead to Doherty leaving the series in 1994. The pair had not spoken for years before filming their first scene together, and commented on the amount of buildup and nerves leading towards their first meeting. Doherty commented, "I think when you're 18, your personalities conflict, then you meet up 10 or 15 years later, and the playing ground is totally different and you're fine."
