Sarah Michelle Gellar Takes a Dip With Dolphins

Sarah Michelle Gellar plays with an Atlantic bottlenose dolphin during a tour at SeaWorld San Diego on Sunday in San Diego, California.

The former Buffy the Vampire Slayer star and her friends were taken on a behind-the-scenes tour where they met penguins, sharks, beluga whales and killer whales.

Sarah, 31, is returning to television with a half-hour HBO project, The Wonderful Maladys, from screenwriter Charles Randolph.

The show is about the lives of three adult siblings, who have relied on each other while growing after their parents died when they were young.

Randolph described Gellar‘s character as having “a kind of zealous immaturity — like a drug addict with a to-do list.”
