Sarah Michelle Gellar is coming back to the small screen — in a comedy. The former Buffy the Vampire Slayer star will co-headline CBS’ workplace comedy Crazy Ones, The Hollywood Reporter has learned. The single-camera entry revolves around the dynamics between a father named Simon Roberts (Good Will Hunting Oscar winner Robin Williams) and his daughter and is set in the world of advertising.

Gellar will play Sydney Roberts, Simon’s daughter. She’s described as pretty, intense, driven, organized and burdened with being practical. Sydney is the creative director and life and soul of the Roberts and Roberts Advertising Agency at the center of the comedy. She wants to be her father but is too busy having to parent him. Boston Legal’s David E. Kelley will pen the 20th Television single-camera pilot and executive produce alongside Dean Lorey, Bill D’Elia, John Montgomery and Mark Teitelbaum. Jason Winer (Modern Family, 1600 Penn) will direct the pilot. Political Animals alum James Wolk also co-stars as Zach Cropper, a copywriter at the agency.

For Gellar, the role marks her second potential series-regular role in a half-hour comedy and comes a year after the CW axed her twin drama thriller Ringer. The actress previously shot an ill-fated comedy pilot for HBO in 2009 that failed to go to series. In addition to her title role in Buffy, the actress has voiced multiple characters in American Dad, Robot Chicken and The Simpsons. On the feature side, her credits include The Grudge and the Scooby-Doo series. She’s repped by ICM Partners, Brillstein Entertainment and Morris Yorn. The casting comes a month after the actress was developing a family comedy written by Men at Work’s Shepard Boucher and exec produced by Apartment 23′s David Hemingson and Margaret Riley. The project failed to move forward.
