PEOPLE.com recently caught up with DiScala to chat about the seedy side of Hollywood and the seemlier side of marriage.
Did you ever imagine you'd be playing Heidi Fleiss?
No! I can't see a bit of myself in it, and I love that. I really hope to become unrecognizable to people as they watch because it's such a departure from anything I've played and just (from) me personally.
So you've never been a prostitute or stolen anything in real life?
Never tried it. Hope I never have to.
What was the biggest challenge for you?
The sex scenes were extremely difficult for me. Although I had a body double, it's still hard. My first day of work on that set was filming my prostitute montage. Literally it's, "Jamie this is Brian, Brian this is Jamie, now go in the shower and pretend you're having sex!" And then it was on to the next scene, and it was another gentleman and I'm on a desk with him. So it was a really strange way to break me in.
What did you find interesting about Heidi as a character?
I had a lot of preconceived notions about her before my research, and I realized that I actually like her. She chose a line of work that I don't necessarily think is right, but she was smart, she was savvy, she was loyal – still, to this day, she has remained quiet about who her clients were.
There's not that much turmoil in your real life, I hope. How's married life treating you?
Married life is wonderful, thank you very much. It's just a blessing for me ... he makes me realize that this is a job. It's difficult to keep grounded in this business, and I think had I not met him, I'd be having a much tougher time dealing with that.
