Gossip Girl
Featuring nine regular speaking roles, the majority of the ensemble cast was assembled from February to April 2007. Leighton Meester and Blake Lively - who started auditioning in December 2006 - were the first two actresses to be chosen in February for the lead roles of Blair Waldorf and Serena van der Woodsen, respectively. Penn Badgley, who had previously worked with Stephanie Savage on "The Mountain", Taylor Momsen, Chace Crawford, Kelly Rutherford and Connor Paolo also auditioned successfully and landed roles in the series in March, as did Florencia Lozano who appeared only in the pilot, and was replaced by Margaret Colin. Badgley had initially turned down the part of Dan. Actors for the roles of Chuck Bass and Rufus Humphrey were found in April when English actor Ed Westwick, and Matthew Settle were cast. Westwick first read for the role of Nate but was then asked to try Chuck. As rumors swirled about the impending cancellation of "Veronica Mars", it was revealed at The CW's 2007 Upfronts on May 17, 2007 that Kristen Bell had narrated the pilot, thus making her the title character of another show on the network. Jessica Szohr was signed on to portray the recurring role of Vanessa Abrams and received regular status during the fourteenth episode of the first season. Kaylee DeFer joined the series in the eighteenth episode of the fourth season and was promoted to series regular for the show's fifth season. At the conclusion of the fourth season, Momsen, who went on an indefinite hiatus during the season while retaining regular billing, and Jessica Szhor both left the show. Throughout the series' run, Connor Paolo consistently declined to elevate his recurring role of Eric van der Woodsen to regular status, citing personal reasons for his decision. After becoming a regular on the ABC series "Revenge", Paolo confirmed his departure from "Gossip Girl" in August 2011. As the show progressed, numerous recurring guest stars appeared in the show. Michelle Trachtenberg signed on to portray Georgina Sparks. The role had previously been offered to Mischa Barton who passed. Francie Swift and Sam Robards took the parental roles of Anne and Howard Archibald, respectively. Caroline Lagerfelt portrayed Celia "CeCe" Rhodes, Serena and Eric's grandmother and Lily's mother.
