Jane, Quinn, and Helen are all voiced by the same actress, Wendy Hoopes.
Daria often describes her perceived cynicism as unabashed honesty. Appropriately, the name "Daria" is Greek and means "upholder of truth."
The character Daria was conceived as a dry-witted comic foil to counter Beavis and Butt-head's stupidity on Beavis and Butt-Head (1993).
Daria does not appear in the 2011 Beavis and Butt-Head (1993) revival. However, it is mentioned and acknowledged that she moved away.
The last episode of the show's half-hour series, the fifth season's Boxing Daria (2001), was written to close out the show. After the creators were offered by MTV an option for another half-season (6-7 episodes) and fans begged for more, co-creator Glenn Eichler decided instead to make a 90-minute TV-movie, Daria in 'Is It College Yet?' (2002), as the official finale.
