Robin Williams is set to star with Sarah Michelle Gellar in a CBS TV sitcom pilot called "The Crazy Ones" according to TV Guide. Expectations run high for a ratings success.

Williams will play Gellar's father who runs an advertising agency with his daughter. It marks Robins return to comedy on TV and provides Gellar's first appearance since 2011's CW show Ringer.

Williams is best-known for his debut hit on the TV show "Mork & Mindy" while Gellar was popular in TV's Buffy the Vampire Slayer and the movie Cruel Intentions. The combination of the two should provide plenty of laughs and bring in both young adults and older viewers, who are longtime fans of Williams.
