For Sarah Michelle Gellar, there's a downside to acting alongside Robin Williams on The Crazy Ones: her struggle to keep a straight face. "It's like when my 4-year-old daughter says something inappropriate, but I can't laugh," says the mom to Charlotte and 12-month-old son Rocky (with husband Freddie Prinze, Jr.).
Sharing such lighthearted moments on set of the CBS comedy, on which Gellar and Williams appear as father-daughter partners in a Chicago advertising firm, helped the costars form an intense bond. Jokes Gellar: "I applied for Robin to adopt me!"
All in all, Gellar can't help but credit the Mork & Mindy TV veteran with making her time on The Crazy Ones' set a fun one. "It can be intimidating when you work with a comic of that level, and the one thing I can attest to with Robin is that he cares almost more about making everybody else comfortable," the actress explains, adding that she's happy "to let Robin take the lead." Says the former Buffy star of Williams: "You have to say, "Go, go -- do your thing," because he really wants it to work with everyone [on set], which is rare."
When Gellar clocks out and returns home to her real family, the actress has a deeper appreciation for the show's flexible schedule. "I take Charlotte to school every day," she tells Us Weekly. "I applaud women who make movies around the world -- but that's not me."
The Crazy Ones airs Thursdays at 9 p.m. (EST) on CBS.
