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.

Original series actors Shannen Doherty, Jennie Garth and Joe E. Tata signed on for recurring roles during early production. Sachs was familiar with Garth, and talked to her about a possible role in the series. Garth agreed to work in the series without reading a script after brainstorming ideas with Sachs. Initially, the producers offered Garth a role as a series regular but, she opted to sign on as recurring instead.
Sachs met with Doherty over dinner, and told her about the "90210" spin-off. Over the next few weeks, they established Brenda's backstory as a 'name' stage actress and Doherty agreed to guest-star in several episodes, appearing in the credits during the first half-season. Otherwise, Doherty only appeared in supporting roles.
