Sarah Michelle Gellar (born April 14, 1977) is an American actress, producer and entrepreneur. After being spotted by an agent at the age of four in New York City, she made her acting debut in the made-for-TV movie An Invasion of Privacy (1983). Gellar made guest appearances in episodes of television series, and had small roles in films, such as Funny Farm (1988). Her first leading part was in the 1992 miniseries Swans Crossing, for which she was nominated for two Young Artist Awards. Gellar's television breakthrough came in 1993, when she originated the role of Kendall Hart on the ABC daytime soap opera All My Children, winning the 1995 Daytime Emmy Award for Outstanding Younger Actress in a Drama Series.
Gellar received widespread recognition for her portrayal of Buffy Summers on the WB series Buffy the Vampire Slayer (1997–2003), which earned her six Teen Choice Awards, a Saturn Award and a Golden Globe Award nomination. The character was widely popular during the airing of the show and became recognized as one of the 100 greatest female characters in U.S. television. Gellar also gained recognition, in 1997, for horror films like I Know What You Did Last Summer and Scream 2. She then played Kathryn Merteuil in Cruel Intentions (1999) and appeared as Daphne Blake in Scooby-Doo (2002), her biggest live-action commercial success.
In 2004, Gellar starred in two box office hits, Scooby-Doo 2: Monsters Unleashed and The Grudge, and subsequently appeared in the 2006 sequel. She then focused on smaller-scale films, such as Southland Tales (2007), The Air I Breathe (2008) and Veronika Decides to Die (2009). She starred in the short-lived TV series Ringer and The Crazy Ones, which co-starred Robin Williams. In 2015, she joined the cast of the animated series Star Wars Rebels for season two.
In October 2015, Gellar co-founded Foodstirs, a food-crafting brand and e-commerce startup selling baking kits for kids.
Gellar met her future husband Freddie Prinze, Jr., while they were filming the 1997 teen horror film I Know What You Did Last Summer, but the two did not begin dating until 2000. They were engaged in April 2001 and married in Mexico on September 1, 2002, in a ceremony officiated by Adam Shankman, a director and choreographer with whom Gellar had worked on Buffy the Vampire Slayer. Prinze and Gellar have worked together several times; they played each other's respective love interests as Fred and Daphne in the 2002 film Scooby-Doo and its sequel, Scooby-Doo 2: Monsters Unleashed, and both provided their voices for the animated features Happily N'Ever After (2007) and Star Wars Rebels. In honor of their fifth year of marriage, in 2007 Gellar legally changed her name to Sarah Michelle Prinze.
Together, Gellar and Prinze have two children. The family lives in Los Angeles, California.
