Chris Marcil is a television screenwriter and comic writer. With Sam Johnson, he wrote the Daria episodes College Bored, The Big House, The New Kid, Depth Takes a Holiday, and Speedtrapped, as well as the pilot, Sealed with a Kick. In an interview, Glenn Eichler says he believed they named Quinn, Jake, and Helen.
Johnson and Marcil also wrote for Beavis and Butt-head and issues of the spin-off comic, many featuring Daria. On the parent show, they suggested a character that would evolve into Todd Ianuzzi and also contributed the term "assmunch" (which MTV initially forced Mike Judge to change it to "buttmunch").
In 2016, he told Paste Magazine: "I remember when we were talking about it we were like, ‘Oh, this is Frasier.’ You’re taking the smartest character from this goofy world and you’re trying to do a show that’s true to that character, not so much true to the world it’s from... We can’t say this is just like Beavis and Butt-head because the audience will see how phony it is and reject it."
Marcil and Johnson's contract with MTV expired by the time Daria aired and they moved out to Los Angeles to work on sitcoms ("where the money was", he told Paste), which is why they didn't take a larger role in the show. He has since worked on NewsRadio, Frasier, and How I Met Your Mother
Chris Griffin is named after him.
