Buffy the Vampire Slayer creator Joss Whedon spoke to USA Today in May 2003 (after the final episode had aired) about his favourite Buffy episodes. They are as follows:

Innocence: “It’s a mission-statement show, and one of the ones where I first found out what we could do.”

Once More, With …

The character of Anya is killed suddenly and violently in the final episode, Chosen. Many fans were disappointed with her death - feeling that it had happened to quickly or that her death wasn’t honoured enough by the Scoobies at the end of the episode. Emma Caulfield, who played Anya, …

Emma Caulfield told a group of Buffy fans at the Starfury Fusion Event (Blackpool, England, 2004) about her experience filming the episode All the Way:
“I actually roller blade, well I haven’t in a while, I used to roller blade all the time and I was an avid skater when …

Joss Whedon teased fans at the Nocturnal N3K Buffy convention by claiming that he’d planned to kill Anya during The Gift. He said the only reason she survived was that Emma Caulfield kept moving in all the footage he shot of Nicholas Brendon holding her at the end.

Emma Caulfield was listed with the regulars in the script for the first time in New Moon Rising, though she was not yet added to the opening credits. She had signed a contract confirming this though. Emma was finally added to the opening credits montage in Buffy vs Dracula. …

Emma played ex-vengeance demon Anya. She was born on April 8, 1973, and her birth surname was Emma Chukker. She is half German on her father’s side and her mother is a singer who is Irish-American. Emma’s older sister, Samantha Killebrew, is a department store manager in San Diego. …

David Boreanaz was the first Buffy cast member to do a scene completely nude - in Faith, Hope and Trick when he returned from hell. Whenever Oz changed into a werewolf before, he remained partially covered, as did Buffy when she was turned back human after being a rat in …

Joss Whedon says in his commentary for I Only Have Eyes For You that it was David Boreanaz’s performance in that episode which made him realise that the actor was strong enough to pull off a spin-off series on his own.

Juliet Landau told the crowd at a Buffy event (Starfury Fusion, Blackpool, England in 2004) about her experience filming scenes in What’s My Line? (Part 2):
“When we were shooting the Buffy episode where David and I are tied together and there was a whole ceremony being performed. And I …

Joss Whedon recalls worrying whether David Boreanaz’s acting skills would be up to the dramatic transformation into Angelus. Boreanaz, Whedon quickly discovered, “plays a bastard with extraordinary aplomb.”

Prior to playing Vampire-With-A-Soul™ Angel, David Boreanaz played ‘Vampire’s victim’ in the film A Macabre Pair of Shorts. He was famously ‘discovered’ whilst walking his dog and cast for the part of Angel the next day. David has appeared n the fourth Crow movie, and starred in the movie Valentine. …
