Document 14: Once More, with Feeling (Buffy the Vampire Slayer): All of the regular cast performed their own vocals, although two actors were given minimal singing at their request. ``Once More, with Feeling ''is the most technically complex episode in the series, as extra voice and dance training for the cast was interspersed with the production of four other Buffy episodes. It was Joss Whedon's first attempt at writing music, and different styles -- from 1950s sitcom theme music to rock opera -- express the characters' secrets in specific ways. The episode was well received critically upon airing, specifically for containing the humor and wit to which fans had become accustomed. The musical format allowed characters to stay true to their natures while they struggled to overcome deceit and miscommunication, fitting with the sixth season's themes of growing up and facing adult responsibilities. It is considered one of the most effective and popular episodes of the series, and -- prior to a financial dispute in 2007 -- was shown in theaters with the audience invited to sing along.
