Thomas later announced that he was leaving the series, and Sachs and Judah were hired to write a new version of the script. Casting began before the script was completed, and several cast members of the original series were approached, of whom several accepted to appear. Reviews of the episode were mixed, and one critic explained, "it's not a great show but it's not a terrible teen drama, not by a long shot. The new 90210 turns out to be a solid sequel with plenty of shout-outs to fans of the old 90210."

The pilot introduces the Wilson family, along with numerous other students at West Beverly Hills High, where Annie Wilson (Shenae Grimes) and Dixon Wilson (Tristan Wilds) begin attendance. Their father, Harry Wilson (Rob Estes), returns from Kansas to his childhood home of Beverly Hills with his family to care of his mother, former television star Tabitha Wilson (Jessica Walter), who has a drinking problem.

Annie hopes to hook up with a friend named Ethan Ward (Dustin Milligan), whom she met two summers ago. When she arrives at school the next day, Annie spots Ethan in his car and makes eye contact, only to realize that he is receiving fellatio from a fellow student. Dixon goes to journalism class, where he meets Navid Shirazi (Michael Steger), while Annie goes to her first class taught by Ryan Matthews (Ryan Eggold).

Annie discovers that she is dating Ethan, and meets her best friend, Adrianna Tate-Duncan (Jessica Lowndes), who is the lead in the school play Spring Awakening. Annie, who is also an actress, is upset that she arrived too late to audition for a role, although Adrianna says that she would be better use backstage. Later, Adrianna takes several pills from a drug dealer, and agrees to pay him two hundred dollars the next day.

Annie sees Ethan and promises not to tell Naomi what she saw. They part ways for lunch, and Annie meets Silver (Jessica Stroup); however, Naomi pulls Annie away, explaining that Silver makes insulting YouTube videos about people. Naomi invites Annie to her birthday party, and they decide to go shopping together. Harry and guidance counselor Kelly Taylor (Jennie Garth) and Mr.Matthews meet with Naomi's parents, who feel that Naomi should not have to hand in her assignments on time when she is planning her party. Before she leaves, Naomi's mother, Tracy (Christina Moore), reminds Harry that they dated in high school. Naomi receives a text message from her mother, telling her that she must complete the assignment that night. Annie remembers that she completed a similar assignment for her old school, and offers to give Naomi a copy for inspiration.

Dixon is accepted into the lacrosse team after trying out, but gets into a fight with team member George Evans (Kellan Lutz). Annie tells Dixon of her invitation to Naomi's party, and how she saw Ethan cheating on Naomi. The next day at school, Annie finds out that Silver made a video blog about her, depicting her as a bitchy farmer.

Annie argues with Ethan because of his lying, and asks what happened to the Ethan that she met two years ago. In class, Naomi reads an exact copy of Annie's paper. Afterward, when Annie confronts Naomi, she apologizes by giving Annie an $800 dress. Annie decides to watch the school play rehearsals, and Silver apologizes for the video by asking the drama teacher to let Annie sing with the chorus for the play. Much to Adrianna's dismay, Annie is allowed to be in the play. Naomi again gets into trouble when Harry discovers that she cheated, and forces her to write the paper in his office.

Production Development On March 13, 2008, it was announced that The CW was developing a contemporary spin-off of Beverly Hills, 90210, which first aired on Fox from October 1990 to May 2000. The project was put on the fast track by the network, and an order of the pilot was expected by the end of the month. The Beverly Hills, 90210 creator, Darren Star, was announced not to be involved with the project, as well as producer Aaron Spelling, who died in 2006. The only surviving element from the original series was the Creative Artists Agency, the talent agency that masterminded the spin-off idea. Veronica Mars creator Rob Thomas was in negotiations to write the pilot, and Mark Piznarski was in talks to direct. "We think this generation of parenting is different than the ones we grew up with. We, as parents, did almost everything that our kids are doing. Our parents didn't do that. It's a lot harder to lie to us. We know what they're doing, and they can't get away with stuff that they think they are because we did it 20 years ago."—Judah on the themes of parenting in the pilot. A detailed breakdown of the pilot written by Thomas was released on March 17, containing information on the plot and characters of the series. None of the characters were related to the original series; however, the series' featured a similar premise: a family with two teenagers who recently moved from the Midwest to Beverly Hills. To reflect the situation at the Beverly Hills school, where around 40 percent of the students were from Persian descent, a student named Navid Shirazi was created. Thomas intended to introduce The Peach Pit, the diner from Beverly Hills, 90210, but noted that it would not be featured in the pilot. The writer considered giving the siblings a job at a movie theater, as he did not want them to use their parent's credit cards. Thomas revealed that there were plans to reintroduce one of the original cast members, but had not met with any of them to discuss a role. Thomas later elaborated 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".

On April 14, Thomas announced that he was leaving the series to focus on his two pilots for ABC. Gabe Sachs and Jeff Judah were hired as the new executive producer and wrote a new version of the script in late April. Sachs said that although Thomas had a "great script", their version of the script was "edgier". Judah said that they were trying to ground their script in reality, with real character stories and emotional stories. The writers wanted the audience to relate to the characters' problems, which they wanted to be truthful and emotional, but also comedic. The pair were interested in telling several stories simultaneously, featuring many characters. The pair changed the surname of the family from Mills to Wilson, and told reporters that they would be adding their "comedic impulses" to the script. Sachs and Judah found the parents to be an integral part of the series, and designed them to be contemporary parents. Since the producers were both fathers, they designed the script to include more prominent adult story lines and a strong point of view on parenting. Judah was interested in focusing on how the family kept their moral center when moving to Beverly Hills, and the way the parents dealt with their teenagers.

Casting

On March 13, Kristin Dos Santos of E! confirmed that the series would be a spin-off with new characters, and not a remake. In order for the project to be ready for the network's "upfront" presentations to advertisers in May, casting began before the script was completed. The first actor to be cast was Dustin Milligan on April 1, followed by AnnaLynne McCord on April 14. Sachs found Milligan to be "really funny", and changed Ethan to better represent his personality. McCord was cast because, according to Sachs, "she's someone who is worldly, and there's a sophistication to her that's interesting". Actress and singer Hilary Duff was rumored to have been offered the part of Annie, but she told reports that it was "not true". The role was eventually given to Shenae Grimes, who says she was raised watching the original series. Sachs and Judah had seen Grimes' work before and knew "she had the acting chops", and she was cast after acting a dramatic scene that she "just killed". Sachs stated, "she can act, she's beautiful, and she can give this sweet cuteness (that lets us see) through her eyes into this world."

Lori Loughlin auditioned for the role of Debbie and was given the part straight away. Sachs thought that Loughlin was too established to read for the part, but realized that she understood the role immediately. The producers were fans of Jessica Walter after watching her film, Play Misty for Me. Sachs found that Walter knew pieces of scenes, and suggested "stuff that works". Sachs described Ryan Eggold, who portrayed Matthews, as "a sophisticated actor, and he's also very funny". Sachs believed that every time Eggold would be on screen, "people are going to go, 'Wow!'".
