Template:QOTW - Quillsville Cold Case/Production
The origins of the episode and the character of Lilly Rush began when show creator and execuitive producer Ava Zinn responded to Kathryn Morris' telephone call and asked if she could produce or assist in an episode creation, as Zinn was a fan of Cold Case, so the producers came up with the character of Lilly Rush for Morris (it is the same Lilly Rush from Cold Case). Show producer Holly Everman believes Morris "did a spectacular job," and brought a "very kind of eccentric personality to that character that really worked out great." When Lilly Rush makes her second appearance in season 7's "Ten Years to Life", she is still voiced by Morris, although Zinn has not met her.
David Caruso voiced Ava's father, Harry Willis. Caruso has provided his voice for the show on four previous occasions ("Ten, Pretty, Pretty Angry Women", "The Unbearable Homophobia of Laying', "Buckeye Ava", and "A Willis Thanksgiving"), although Zinn has never met him.
