Sarah Michelle Gellar, David Boreanaz Celebrate 25th Premiere Anniversary Of ‘Buffy The Vampire Slayer’

Sarah Michelle Gellar still prides herself on playing a teenage vampire slayer in one of the most-watched TV series in the late ‘90s.

Gellar, 44, shared throwback snaps on the set of “Buffy The Vampire Slayer” as a tribute to the show’s 25^th premiere anniversary Thursday.

"25 years ago today I had the honor to introduce the world to my version of Buffy Anne Summers. It was an uphill battle," she wrote alongside two images of herself as Buffy. "A mid season replacement, on a new network based on a movie, that was by no means a giant success. But then there was you. The fans. You believed in us. You made this happen. You are the reason 25 years later we are still celebrating. So today we celebrate you as well. #wwbd," she added.

Michelle Trachtenberg, who played Buffy’s sister, Dawn replied, “Congrats big sister. There was no [sic] without your Magic.”

The supernatural drama series was created by Joss Whedon and ran for seven seasons from 1997 to 2003. The story revolved around Buffy, her generation’s chosen slayer of vampires, demons and other dark forces. Together with the help of her friends, known as the "Scooby Gang," Buffy and company fight one evil after another while attending high school and college.

David Boreanaz, who played Irish vampire-turned-private investigator, Angel also shared a throwback photo of himself from the show. He wrote, "An Angel was born 25 years ago even though he was 245 years old. We celebrate 25 years and to all the fans we say 'Thank You!'”

Angel was also Buffy’s love interest for a certain period in the series. Boreanaz left the show and starred in the spin-off, “Angel” which ran from 1999 to 2004 with “Buffy” alum, Charisma Carpenter.

Gellar replied in the comments section, "My angel - then and now."

Carpenter also reflected on her time on the set of the show and thanked fans who continue to support the show.

“25 years ago hardly seems possible! A huge thanks to fans the world over who have kept the show alive onscreen, in chat rooms, across social media platforms, through podcasts and school curriculums… it’s truly remarkable,” she wrote in an Instagram post.

All seven seasons of the series are available for streaming on Hulu.
