Alyson Hannigan Honors 'Buffy' Co-Star Anthony Head Following His Death

Alyson Hannigan is mourning the loss of her longtime Buffy the Vampire Slayer colleague Anthony Head, who died at age 72.

The actress shared her remembrance on Saturday, June 6, following an announcement from Head's daughters that he had succumbed to complications from pneumonia. Posting a cherished photo of the two together on Instagram, Hannigan expressed the depth of her grief and gratitude.

"This cut is so deep I fear it can never heal," she wrote. "Oh Tonal…I am so grateful to have had you in my life! I want to say a million wonderful things about you and yet I can't seem to find the words that would do you justice. I love you so much and will miss you forever. RIP."

Head earned lasting recognition among Buffy devotees for his role as Rupert Giles, the steadfast Watcher and guide to Sarah Michelle Gellar's protagonist. Throughout the series, his character forged a meaningful connection with Hannigan's Willow Rosenberg, serving as a mentor figure as the young witch developed her magical powers and navigated profound personal challenges.

The loss marks another difficult chapter for the Buffy ensemble. Earlier in 2026, Nicholas Brendon, who brought Xander Harris to life in the supernatural series, passed away at 54.

Gellar also shared her own heartfelt remembrance of Head.
