Jill Hennessy recorded songs for the show's soundtrack.
The launch of the third season was delayed for about half a year to accommodate Jill Hennessy's real-life pregnancy.
Executive producer and creator Tim Kring was at first reluctant to cast Jill Hennessy as the impulsive, abrasive medical examiner Jordan Cavanaugh, knowing only her work as the straight-laced Assistant D.A. Claire Kincaid on "Law & Order" (1990) and as Jackie Kennedy in Jackie, Ethel, Joan: The Women of Camelot (2001) (TV). Agreeing to meet for breakfast, Kring was embarrassed to discover the restaurant he had chosen was closed when they arrived. Kring started to apologize, but Hennessy, unfazed, said, "Dude, who gives a shit? We'll go someplace else." Kring recalled thinking, "Oh, my God, this is Jordan."

Jill Hennessy is such a fan of the folk duo Indigo Girls that a poster of the act hangs in the kitchen set of her character.
