Taraji P Henson is driving down a Los Angeles street, chatting on her mobile phone, when a billboard catches her eye.

“Hi, me! Hi!” she says, smiling at her latest on-screen incarnation: the glamorous ex-con Cookie in Empire, which is scheduled to debut next month on OSN First HD (as well as OSN on Demand and OSN Play).

Draped in fabulous furs and drenched in attitude, Henson’s Cookie is the heart of the Fox drama, a fiercely devoted mother and astute businesswoman who’s fearless when it comes to getting what she wants. Her sometimes-reluctant partner is Lucious Lyon (Terrence Howard), a music mogul deciding which of their three sons should run the family’s entertainment empire.

Henson has seen her face on billboards before, with dozens of film credits (including 2008’s The Curious Case of Benjamin Button, for which she earned a supporting-actress Oscar nomination) and popular TV series, such as Person of Interest, to her name.

“Sometimes I forget, you know what I mean?” she says. “I just go on about my day, and look up and go: ‘That’s right, I do have a TV show coming out.”

The 44-year-old actress, who this month returned to Person of Interest for a guest-starring role and hosted Saturday Night Live for the first time, talks about her role on the first-season smash hit – and the empire that is Taraji P Henson.

qWho is Cookie?

aShe is a hero. I mean, she is the truth. She is strong. She’s family first. She’s a lot of things. She doesn’t compromise at all – never herself and never her truth. That’s what I love about her. She says things that I might not have the guts to say. I love the way she dresses. I love how much she cares about her sons.

How is it working with Terrence Howard again, your old pal from Hustle & Flow?

I just know that I really like working with Terrence. I trust him. And for me as an artist, acting, you really have to be uninhibited. You cannot have any hang-ups. Or if you do, they can’t breathe and live through these characters, because their hang-ups aren’t your hang-ups. So for me, to fully explore characters without throwing Taraji in the mix, I have to feel safe. And with Terrence, I’m so safe with him, I can try anything. We’re friends. We’ve known each other, so it really works for Cookie and Lucious. When they came to me with the project, I said it has to be Terrence. When I cracked open the script, I saw no one but Terrence.

What’s most challenging to you as an actress right now?

Challenging is getting what I think I deserve to be paid. [It’s] challenging to get the projects I want done or greenlit. I’m still having to prove I’m bankable. But I think it’s getting better. I’m not one to wallow in the muck. I don’t harp on how bad things are. My thing is to prove each and every time I’m on the screen – whether it’s TV, whether it’s film, whether it’s the stage – Taraji is going to deliver. So when I do get that moment – because it’s coming, I work too hard – that perfect movie comes along and some studio is going to say: “I believe in her.” Not me and a man. Not me and another guy, no. Taraji P Henson is going to open this film. Then I know that I’m doing my job.

There will be a marathon run of all 12 episodes of season one of Empire on OSN from May 21 to 23 at 11pm and it will also will be available on OSN on Demand and OSN Play
