made her debut appearance in this episode as New York socialite
Renee Perry. "Remember Paul?" was written by series creator and executive producer
Marc Cherry and directed by David Grossman. It marked the debut of Vanessa Williams as Renee Perry, an old college rival of Lynette Scavo. The addition of Williams to the cast was announced after the close of the series'
sixth season, as well as the finale of the ABC series
Ugly Betty, in which Williams starred as
Wilhelmina Slater. The character, who was originally named Renee Filmore-Jones, was conceived as a trouble-making vixen, similar to the
Edie Britt character (
Nicollette Sheridan), who appeared on the series until the
fifth season. Following the casting announcement, Williams admitted to having been a fan of the series during its first year, but stopped watching because of the racially insensitive
second season mystery storyline. It focused on
Betty Applewhite (
Alfre Woodard), the series' first black main character. Williams explained to
Entertainment Weekly, "[Betty] had her son in chains in the basement. It was like, 'Really? Do we have to go there with our first Black character?' I honestly fell off the show after that. I think it was just so implausible and just an image that Black folks don't want to see their child chained and shackled in the basement." Cast member Felicity Huffman commented on Williams' addition to the cast, saying "She's such a great dash of vinegar to Wisteria Lane! It's going brilliantly—she's a wonderful woman, she's really smart, she's really strong, a real team player. She's a great addition." The episode also reintroduced the storyline of Paul Young and Felicia Tilman's rivalry. Mark Moses returned to the series as a series regular after appearing briefly as Paul in the
sixth season finale. On his return, Moses commented, "There was some talk about [me coming back] a year ago. And there’s often talk in Hollywood. Sometimes it pans out, sometimes it doesn’t. I don’t get super-excited about a 'maybe' in this town, because there are lots of maybes that don’t happen. But then this last year they called up my agent and said, 'We're really thinking seriously about [this].' And eventually, they made an offer, and I was very pleased." while Steven Culp and Christine Estabrook returned as Rex Van de Kamp and Martha Huber respectively in flashback sequences. Kyle MacLachlan, who left
Desperate Housewives as a series regular at the end of season six, reprised his role as Orson Hodge in this episode.
Kevin Rahm and
Tuc Watkins, who have been portraying gay couple
Bob Hunter and
Lee McDermott since the series'
fourth season, were both promoted to series regulars for the seventh season. Darcy Rose Byrnes also joined the main cast as Penny Scavo, a role previously portrayed by Kendall Applegate. Brian Austin Green made his series debut in the episode as Keith Watson, "a new contractor and charming playboy" who catches the attention of both Bree and Renee, while Lainie Kazan began a multi-episode guest appearance as Maxine Rosen, Susan's landlady. ==Reception==
