Former 'Buffy the Vampire Slayer' actress Sarah Michelle Gellarhas signed on to co-star with comedic actor Robin Williams, 61, in an upcoming CBS sitcom 'Crazy Ones.'
The premise of the comedy will have father and daughter operating the Roberts and Roberts Advertising Agency. Gellar's character Sydney is the company creative director who spends much of her time parenting her father Simon.
Co-starring as a copywriter at the agency is 'Political Animals' actor James Wolk.
A pilot is in the works that will be directed by Jason Winter of 'Modern Family' and '1600 Penn' fame.
Like all pilot projects, it will be up the the network to give the green light for additional episodes or declare it DOA. Gellar has experienced the latter first hand after a family comedy that she was recently developing failed to move off the starting block.
The 35-year-old has been married for a decade to Freddie Prinze, Jr. They have a daughter Charlotte, 3, and an infant son Rocky who was born in September 2012.
