Some Velvet Morning features just two characters — Velvet, a prostitute played by Alice Eve, and Fred, a john portrayed by Stanley Tucci — who engage in a meandering, circuitous, confounding, and regret-charged conversation. They have a history, despite the decades that separate them, and Fred's return to her apartment after several years of absence makes for an awkward and fiery interaction. It is more or less a play on film, the scenery limited to the various rooms of Velvet's apartment.

Control passes back and forth between Fred and Velvet as they poke each other with heated barbs about jealousies and past mistakes. Details of their relationship become apparent in dribs and drabs, and it seems that Velvet still sees Fred's son — in both personal and professional settings — which only adds to the unconventional nature of their semi-undefined relationship.

"I was interested in parameters of love — How far does love stretch? What is it that makes someone say, 'I'm in love with this person,' and I believe them?" LaBute said. "Fred and Velvet's is not the type of relationship that one would usually see or accept, so does that mean they're not in love because it's hard for me to believe it? Does it mean I look at it and say, Well, there must be something else going on there. He's so much older than you, or you're so much better looking, or you're so much more famous. There must be something else going on?"

For Eve, the script came at a time when she was looking to do a "darker" project. The intimate and intense Some Velvet Morning production piqued her interest since it followed her experience playing the Enterprise's Carol in the massive CGI extravaganza that was Star Trek Into Darkness. The actress said Velvet intrigued her because she couldn't quite understand where the character was coming from.

"She's entered into a fight with a guy she knows is ultimately physically stronger than her, and she's playing him hand-for-hand at his own game," Eve explained. "I guess it's a form of addiction. You can watch a heroin addict go through the process of taking heroin, and then, you're like, Well, that looked horrible. They'll never want to do that again. I know that for sure… and then they're doing it again. That's something that we probably still don't understand. We call addiction a disease; we don't understand it yet. It's a crazy thing."
