Former "Buffy" and "Ringer" star Sarah Michelle Gellar will play Robin Williams' daughter in the David E. Kelley workplace comedy pilot, "Crazy Ones," at CBS.

According to The Hollywood Reporter, "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, who is described as "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."

Kelley is writing the pilot and will executive produce alongside Dean Lorey, Bill D'Elia, John Montgomery and Mark Teitelbaum. Jason Winer ("Modern Family," "1600 Penn") will direct the pilot.
