Production Details
Writer Jane Espenson explains the Buffybot was introduced out of "the necessity of story", as it was "interesting to see what Spike would do with this bot... to see how those personalities affect each other." Providing Sarah Michelle Gellar with the chance for comic relief during a period of particular grimness for her character was a "bonus... an extra scoop of ice-cream," says Espenson.
In the fight scenes in "Intervention", Xander was played by Nicholas Brendon's identical twin, Kelly Donovan, because Nicholas suffered from pneumonia at the time.

Famous quotes containing the words production and/or details:
“In the production of the necessaries of life Nature is ready enough to assist man.”
—Henry David Thoreau (1817–1862)
“There was a time when the average reader read a novel simply for the moral he could get out of it, and however naïve that may have been, it was a good deal less naïve than some of the limited objectives he has now. Today novels are considered to be entirely concerned with the social or economic or psychological forces that they will by necessity exhibit, or with those details of daily life that are for the good novelist only means to some deeper end.”
—Flannery O’Connor (1925–1964)
