Twenty-five years ago, on November 6, 2001, Buffy the Vampire Slayer aired its seventh episode of the sixth season, an installment that would go down in television history: "Once More, With Feeling." This Emmy-winning musical episode, masterminded by creator Joss Whedon, is frequently cited by fans as one of the show's finest achievements. The brilliance of the 50-minute spectacle lies in its innovative use of a demon's curse, compelling everyone in Sunnydale to sing and dance, thereby advancing the show's intricate plotlines in ways that conventional dialogue could not.

One of the most significant narrative threads explored was the complex relationship between Buffy (Sarah Michelle Gellar) and Spike (James Marsters). Their toxic, on-again-off-again dynamic reached a new level as Spike, compelled by the curse, finally aired his deep emotions through song, leading to their first genuine kiss once the enchantment lifted. James Marsters, reflecting on the episode's creation and legacy, shared his behind-the-scenes perspective.

Genesis of a Musical

Marsters recalled that the cast did not receive a typical script for the episode. Instead, they were given a cassette tape featuring Joss Whedon singing the songs and playing them on the piano. Marsters, a punk rocker at heart, initially found the demo unconvincing, describing it as "cheesy" and expressing a sense of panic among the cast.

"We were given a cassette tape with Joss singing the songs of the show and plunking them out on the piano," Marsters said. "And whereas Joss is an enormously gifted writer and director and producer, as a singer he wasn't quite up to the material. It just sounded cheesy. I'm a punk rocker, and I was like, ‘What the F is this?’ It just set off this deep panic as we discovered that we were going to be asked to suddenly do a musical."

While Marsters and Anthony Head (Giles) had prior professional singing experience, most of the cast members were apprehensive. "I'm not a singer. You hired me to be a one-camera dramatic slash comedic actor, and that's what I do," Marsters recalled actors saying. "And now you're gonna have me go out in front of tens of millions of people... and do something that I'm not a professional at. You're gonna ruin my career."

Despite the initial fear and resistance, the cast eventually accepted that the musical episode was happening. This acceptance led to a remarkable level of dedication, with many cast members hiring their own vocal and dance coaches.

"People started hiring their own vocal coaches and their own dance instructors on their own dime," Marsters explained. "All these people were showing up to set. People were rehearsing and preparing in the middle of filming the previous episodes." The turning point for many came after seeing an early cut of the Xander-Anya sequence, which proved the episode's potential.

Spike's Musical Moment

Marsters' own contribution, the song "Rest in Peace," presented a particular challenge. He found his way into the song by experimenting with guitar chords, which led to a vocal style he felt captured Spike's frustrations. Although producers initially suggested a more Broadway-rock sound, Marsters insisted on his interpretation.

"I brought my guitar up to the production offices and I was like, ‘I found it! This is how we gotta do it,’ and I started playing. The producers go, ‘That's amazing, James. That would be like if Nirvana did the song.’ I was like, ‘Exactly!’ And they said, ‘No, this is not Nirvana. This is like a Broadway rock song. So it's got to fit in.'" Marsters recounted, "And I was like, ‘F you guys. I'm gonna sing it that way anyway.'"

He elaborated on the song's significance for his character: "There's a lot of frustration pent up in Spike. Buffy has been kind of, ‘Come here, get away from me. Come here, get away from me.’… Thank God I get to express it. How wonderful would it be to just break out into a song and say, ‘Babe, either take me or don't. You're just torturing me right now.'"

Marsters highlighted the power of musicals to convey emotions that dialogue cannot.

"Joss knew that and he used that to get his characters to say things that they normally never would tell each other — secrets that people keep hidden from each other — and the chaos that can happen if that stuff is let out all in one day."

Enduring Legacy

"Once More, With Feeling" remains a fan favorite and is widely considered one of the best television episodes ever made. Marsters attributes its success to the show's core theme of perseverance in the face of hardship.

"The theme of Buffy is: Don't give up. It's hard to be a human being. It hurts to be here. The world is very imperfect, but don't give up on yourself. Don't give up on the world. Find something to fight for," Marsters stated. "For one episode, we spoiled Hollywood actors lived up to the theme of the show. And then, luckily and wonderfully, it didn't suck."
