Sarah Michelle Gellar Honors Late 'Buffy the Vampire Slayer' Co-Star Anthony Head

Sarah Michelle Gellar has taken to social media to honor Anthony Head, her co-star from the beloved supernatural series 'Buffy the Vampire Slayer,' after his passing.

On Friday, June 5, Anthony's daughters Daisy and Emily announced that the actor had "passed away peacefully of complications due to pneumonia" at the age of 72.

The 49-year-old actress posted a touching message on Instagram shortly after news of his death became public. "'Tell Giles I figured it out and I'm ok.' Well I don't have it figured out and I'm not ok," Gellar wrote, referencing her character's relationship with Head's character. "But I know I'm the lucky one because I knew you. Thank you to Daisy and Emily who not only shared their dad with me, but with the world."

She accompanied her tribute with several photographs featuring Anthony, including images alongside their fellow cast members, as well as pictures with her husband Freddie Prinze Jr. and her daughter Charlotte.

Throughout the series, Head portrayed Rupert Giles, the Watcher tasked with overseeing and guiding Gellar's Slayer character, Buffy Summers, on behalf of an ancient British council.

Beyond his iconic role on the show, Head gained additional recognition for his work on the sports comedy series 'Ted Lasso,' where he played Rupert Mannion, the ex-husband of Rebecca Welton, portrayed by Hannah Waddingham.

The entertainment world has mourned the loss of numerous cast members from 'Buffy the Vampire Slayer' since the series concluded in 2003.
