Who Is Ryan Kiera Armstrong? Everything You Need to Know About the Star of the ‘Buffy’ Reboot
Ryan Kiera Armstrong has taken on the role of the new slayer in the upcoming revival of “Buffy the Vampire Slayer.”
The 15-year-old will star alongside the original series lead, Sarah Michelle Gellar.
On May 15, the two actors announced the news in a joint Instagram post, featuring a video where Gellar shared the casting news with Armstrong.
“How do you feel about helping me save the world?” Gellar, 48, asked Armstrong in the clip.
“Good,” Armstrong replied, appearing uncertain about Gellar’s intent.
“Do you want to be my Chosen One?” Gellar inquired, prompting Armstrong to cover her mouth and burst into tears.
“Will you stand by my side and save the world with me?” Gellar continued, as Armstrong, still sobbing, nodded in agreement.
“Ryan, we all love you,” Gellar expressed. “From the moment we saw your audition tape, you stood out as the one we wanted to take this journey with. I am so excited to be by your side.”
“This is so exciting. Oh my gosh,” Armstrong exclaimed, looking around in disbelief. “Yes, yes. Absolutely, yes. Um, thank you. I’m so excited.”

“What do you think? Are you ready for this journey?” Gellar asked Armstrong’s dad.
“I know this is where she’s meant to be right now,” he replied proudly.
In her post’s caption, Gellar wrote, “I want to introduce you to @ryankarmstrong. From the moment I saw Ryan’s audition, I knew there was only one girl I wanted by my side.”
